When my seven-year-old photo editing laptop started mysteriously turning itself off, I knew it was time for a new one. I can't say I was excited. The cost of a new computer would be high, especially one that had the power to keep up with my photo editing. Living on a tight college budget only complicated things further.
However, as a professional photographer, it is imperative that I have a laptop that can download and edit my photos. After my Apple college student discount, the computer I wanted was going to cost $3,096. I could have just settled for 3,096 points on a card that earns 1 point per dollar. However, I knew I could get more points -- 18,651 more, to be exact.

Cashback Monitor
Cashback Monitor is one of my favorite points and miles hacks, and one that I use daily. It's a free site that allows you to track the best shopping portals, credit cards and cash-back services to maximize purchases at select stores.
Knowing I had some time before my computer needed to be replaced, I decided to try and line up my $3,096 MacBook Pro purchase with a shopping portal sale. It took a few weeks of checking Cashback Monitor until one morning I saw that United Airlines MileagePlus Shopping was offering 5 miles per dollar spent on Apple purchases.

It wasn't the best-ever offer for the Apple store, but I needed my new laptop soon, so I took it. And I earned 15,480 United MileagePlus miles.

Which credit card I used
I decided to use The Blue Business® Plus Credit Card from American Express to earn 2x on my purchase (on up to $50,000 per calendar year). That's 6,192 Membership Rewards points added to my account. On top of that, my Blue Business Plus card offered $25 back on all purchases over $500 through the beginning of July.

And bonus -- with this purchase, I got a free pair of AirPods (normally $199) along with my new MacBook Pro, 15,480 MileagePlus rewards and 6,192 Membership Rewards points. It may not have been the best sale that TPG has seen with Apple, but for a purchase that was becoming increasingly urgent, I am happy with what I got.
Redeeming those miles
Those 21,672 total points and miles are a great return on my purchase. I've already used some of them for my next adventure.
I transferred 6,000 Amex points to Delta SkyMiles. It wasn't the best use of points, but I was able to top off my account for a flight on Hawaiian Airlines from Honolulu to Kona to visit a friend on my next trip. Using 7,500 of my Delta SkyMiles allowed me to save $120 instead of purchasing a last-minute ticket.

As for my 15,000 United MileagePlus miles, I plan to use 9,700 of them for a one-way reward to Chicago this fall to catch a Cubs baseball game. Tickets right now are $230, so that's not a terrible redemption right there at 2.4 cents per point.

Bottom line
Having to make an unexpected large purchase is unfortunately part of being an adult. However, there are ways to maximize even the biggest purchases. Knowing which cards are best for specific purchases and using resources such as Cashback Monitor are ways we can at least soften the blow. I was able to earn 21,672 points, a free pair of AirPods, a $25 statement credit and a pair of free flights. Thanks to buying a computer I needed anyway, I'll be enjoying some fun daytrips!
