Lots of vendors send stickers. I've been saving them for quite awhile. My wife makes fun of my sticker obsession. I just needed just the right place to stick them. Found it today
I cheat a bit. I put the stickers on, without removing the backing, to those thin, self adhesive magnetic sheets they use for photos. That way I can keep them on my metal shop cabinet.
I have a similar situation. I order a lot of my car parts from Rock Auto (You absolutely will not find better prices for top quality car parts).
Anyway, they ship a magnet with each shipment. The magnet is usually a picture of a collectible car, restored using parts from them. Since they're magnetic, I stick them to the underside of my Grizzly air filter.
