I have a hobby I enjoy called saving money. It doesn’t take much time and can even help fund my other hobbies.

The short version is – if I’m going to spend money anyway and 5 minutes of effort will reduce the cost, I might as well do it.

Here are a few recent examples.

Fun Money Hacks I Have Done Recently

Travel

Travel is fun. Paying less for the same travel is more funner.

Flights

We are going to Mexico for spring break this year. When Google flights finally notified me that the price had dropped below my target I made the purchase.

Savings for waiting: $41 * 4 = $164

But… the price on the airline website was $30/person higher than what I saw on Google. Why? Turns out the price for booking 4 seats in a single reservation was higher than making two reservations for 2 seats.

So we have 2 reservations.

Savings: $30 * 4 = $120

Checked Baggage Fees

We have one of those airline credit cards with an annual fee ($75.) I was going to cancel it before this year’s annual fee came due… but then I bought those 4 tickets to Mexico.

Since we travel with 2 kids we almost always check bags (typically two of them.) It’s just way more convenient. Well… said airline card waves all baggage fees, so I am keeping this card for another year.

Savings: $35 * 2 bags * 2 flights (roundtrip) – $75 annual fee = $140 – $75 = $65

Cash Back on Hotels

I booked our Mexico hotel back in October when Rakuten was offering 2% cash back on hotels.com (typically 1%, excluding taxes and fees.)
(Good thing too because now the hotel is sold out for the length of our stay.)

Total was $1,192.68, or $909.44 for the room plus a bunch of taxes. 2% back on that $909.44 will earn $18.19 once we complete our stay.

I made this payment via Paypal with my Chase Freedom card since Paypal was a 5% cash back category in Q3’23, which earned $59.63.

Savings: $18.19 + $59.63 = $77.82

If you haven’t used Rakuten before you can get $30 cash back after you spend $30 (on the stuff you were buying anyway.) (affiliate link)

Just Because of 5% Interest Rates

Once interest rates drop I’ll have to find another way to entertain myself, but in the mean time…

Pay in 4 via Paypal

Usually when I pay for something via Paypal I automatically select the Pay in 4 option. This splits the cost into 4 payments, 1/4 up front and then 1/4 biweekly (~6 weeks total.)

All this means is that a purchase is now spread across at least two (but sometimes 3) credit card billing cycles for a 60 to 90 day delay. It is nice for cash flow management.

If on average I get a free loan for an extra 60 days, then I can keep that money in my cash account a little longer earning 5%.

In this purchase history I spent $2,580.73 x 5% * 60/365 = $21.21

It’s not much… but it happened automagically with the click of a button so the hourly rate was good.

Savings: $21.21

Time Shifting via Pay in 4

A greater benefit was had just from time shifting 3 of the payments into Q3… so instead of 1% or 1.5% I was able to get 3% on 3/4 of this purchase.

Savings: 3*$193.01 * 5% = $28.95

My Chase Plan®

Chase credit cards offer a pay over time feature which they promote as “no interest” but with a monthly fee. How that is different than charging interest is beyond me, but what can you do.

But sometimes… that fee is zero. I don’t know why or when, but multiple times now I’ve been able to snag some good interest free loans. Most recently I paid some property taxes on my Freedom card solely because I was being offered these no fee pay plans. Now I have 2 years + 2 months of 0% interest

I’m skeptical that I will be able to earn 5% for the next 24 months due to Fed rate cuts…. but if I can, I’ll get $310.

Playing the Spread

With his/her new Discover credit cards we were able to borrow ~$19,500 for 18 months+/0 at 0% interest. I invested this in short-term treasuries yielding 5%+

See: Playing the Interest Rate Spread for an Easy $2,000

Earnings on investment: $19,500 * 5% * 1.5 years = $1,462.50 (plus another $500 in cash back on purchases)

3% Balance Transfers

That airline card I mentioned at the beginning of this post… they just recently offered balance transfers with 0% interest until February 2025 (13 months) with a 3% balance transfer fee.

It’s not 0%… but what the heck, I’ll take the 2%-ish delta and put that in my pocket. I had done this previously ~18 months ago with ~$25k when the SP500 was 25% lower so as to avoid selling stock during a significant downturn.. and now those balances are coming due with about $10k remaining.

Total fee: $300
Interest earned on $10k for 13 months: 10k * 5% * 13/12 = $542

Total earned: $242

Gift Cards

These were easy and rewarding

Airbnb Gift Card at Costco

We are going to Europe this summer for a few weeks and are staying in some Airbnbs. Over Christmas, Costco was selling $500 Airbnb gift cards for $450.

The only downside was it was only one per customer.

Savings: $50

Target Gift Card

Every December as far back as I can remember, Target has an offer for a single $500 gift card for $450.

Since we routinely spend more than $500/year at Target I usually pick one of these up.

But this year… Target purchases were one of the 5% cash back categories on Discover cards, so of course I made the purchase on that card. And since Discover is offering 2x cash back on all purchases for the first year… the savings are a little higher.

Savings: $500 – $450 + 10% cash back = $50 + $45 = $95

Starbucks Gift Card

Around Black Friday Starbucks had a promotion where you got a $5 gift card if you purchased a $25 gift card. We don’t really do Starbucks much because coffee at home is so much better, but I do like a peppermint mocha around the holidays. We also occasionally stop for a hot chocolate after a snowboarding trip.

Then I accidentally found out about a promotion where you could get a $3 grande beverage every Thursday afternoon in January… and by coincidence Jr had some sports stuff on Thursday afternoons just near a Starbucks, so I used this weekly.

Savings: $5

Lowe’s Gift Cards via Target Circle

Every once in awhile Target has a promotion… complete 3 separate transactions of $100 or more and get $30 credit for future Target purchases.

I use this to buy Lowe’s gift cards whenever I have a project underway (almost always?)… by paying with our Target credit card we get 5% off, so I can buy a $100 gift card for $95.

Do that 3 times and I get an extra $30.

Total savings: 3 x $5 + $30 = $45 (Ultimately 15% off on everything at Lowe’s – or anywhere really.)

Not included in my math here, but sometimes these can be stacked with other offers for extra savings

Bonuses

Getting paid to click a few buttons on the phone.

Amex Send & Split

Amex Send & Split had a promotion where if you sent $30 to a Venmo user they gave you $10. You could send it to anybody so I just sent it to my wife… keep it in the family, ya know?

It only took 3 minute to setup and I now use it all the time for paying the nice people who clean our house via Venmo.

Earnings: $10

Pay Utilities with a Credit Card

A few different times now we’ve had an offer to get $10 for paying a $100 utility bill on Chase cards. It takes me 2 minutes to click the enroll button and then point the autobiller to a different credit card.

Earnings: $10 * 3 = $30

Notably Absent – Bank bonuses

In the past when interest rates were 0% I would occasionally jump through some hoops to get a bank bonus… the process is typically:

  • open a new bank account
  • deposit some money for a period of time
  • get paid hundreds of dollars

But when interest rates are 5% and these new bank accounts typically pay nothing aside from the bonus, it just isn’t worth it to move money around imho.

See: Bonus Season!

For the Long Term

A good(?) move when interest rates were low and inflation was high.

Investing the Mortgage

I borrowed money against the house at 2.75% and invested it, primarily in the US stock market. As of the end of 2023 we are up $3,170 after accounting for all income and expenses.

Probably this year the dividend income will start to completely cover the interest expense and over the next 28 years inflation will do its thing in our favor.

Summary

I have a fun hobby that makes a little money and that I can do in the car while waiting for kids to finish school or sports. Silly? Certainly. Irresponsible? Probably.

But just in the examples above I’ve got $1,257.98 in savings or interest, another $1,462.50 from our Discover credit card loans (plus the cash back, not included), and $3,170 in investment returns from investing the mortgage.

Add that all up and we are talking some real money. Clickity click $ $
