One thing that I like to have around are some inexpensive precut mats so that I can easily print out and mount a photo for someone.

One of my favorite artsy stuff store (Hobby Lobby) has an online 1/2 price coupon for precut mats for the next week.
They also have a weekly sale sheet that often includes other items I need ( frames and painting stuff) at 1/2 or 1/3 off. I get the weekly coupon and sale sheet emailed to me each Sunday.

It looks like they have some stores throughout the midwest and south, here in the midwest. It's a fun store to browse through and I'm also tempted to ask them to allow me to photgraph stuff in there displays.
