Office Max is the BEST place to get free office supplies!
They have a rewards program called Max Perks (sign up here) where you get a certain percentage of your purchase back in the form of spendable rewards. As of today (I'd call 1-866-MaxPerks to confirm) you CAN use your rewards to purchase gift cards in the store!
There are 2 ways to sign up: as a business or as a teacher (these do NOT have to be official titles). The main difference between them is that the teacher's account issues the rewards quarterly (way too slow) but gives you a $10 reward for every $75 on qualifying purchase, while the business account issues the rewards monthly but only issues a $25 bonus on $500 in qualifying purchases. The business account is, in my opinion, the way to go. Office Max has "free after MaxPerks Rewards" deals quite often, and if you are sitting there waiting for your rewards to show up in your teacher's account, you could be missing some great deals!
The single most important detail about the Office Max rewards is that THEY DO ROLL OVER! Which means, if you have $75 in rewards in your account and make a $50 purchase on items that offer 100% back, you can use your rewards and you will get more rewards back!
So, what's the best way to use Office Max?
Here's what I did: About 6 months ago, I made an initial "investment" of around $50. I got a few boxes of pens, a couple of binders and some labels. Then, about once a month, I will (using my rewards) take advantage of more "free after MaxPerks Rewards" deals they have going and get more stuff while keeping my rewards rolling. On one order, I spend about $20 more bucks in actual money, so now I am rolling about $70 in rewards.
