Our local grocery store recently ran a promotion. They ordinarily run a deal with their in-house gas station - for every dollar spent, you get a point. For every 100 points, you get ten cents off a gallon of gas. If you have 1,000 points, you get a dollar off of gas. Every week, however, they run an extra bonus - like if you spend $15 on certain products, you can get an extra 300 points. We've often gotten large discounts on gas for our cars this way.
In recent weeks, if you bought gift cards there, they offered 4 points for every dollar spent - a $25 gift card would earn 100 gas points. We bought a few gift cards as gifts, but the real winner here was my mother-in-law. She was planning on upgrading her washer and dryer, so she bought $1,000 in Home Depot gift cards to pay for the machines, and she also bought quite a few gift cards to places like Kohls, to use for her Christmas shopping. She used our club card for some of the purchases, so she and we were both able to get free gas!
If you were already budgeting and planning certain Christmas purchases in different stores, and your grocery store offers this promotion, your Christmas purchases could also keep your car in gas.
Of course, if you're a dedicated cyclist, this is the kind of advice you scoff at from under your balaclava as you pedal through the slush to get to the store! But if you're a semi cycling wimp like me, getting that free gas is a huge bonus so you can get to places further than 2 miles.
