Yes, and when I first came back into shopping I used my reimbursements to buy some decent maps of the area because MapQuest and a Rand McNally maps were the only ones available on the internet and they were far from accurate. Now, of course, we have a variety of websites for mapping as well as GPS in a lot of different forms.
Of course there are other things you could purchase. In terms of grocery type items, they are cheaper at the grocery where I can do shops and use coupons. Automotive items can be bought on competitor shops at Walmart or at Big Lots when they have their weekends with 20% off everything in the store. We used to even have auto parts shops, though I haven't seen those in a while.
I have been known to schedule gas stations or grocery shops for Sunday mornings to purchase a few copies of the Sunday paper for the coupon inserts. There are always lots of ways to skin a cat and it comes down to efficiency in making the most of your reimbursements.
