I saw this on slickdeals. Sticker mule has a sale going on where you can order 10 custom 3x3 stickers for $1 shipped. Just upload your art and they will send you a proof for approval. I ordered 2 orders under one email before it said I had reached my limit so I went to another email and it let me place another order. I have not ordered from stickermule before so I can't vouch for whether this company is any good. The stickers are supposed to be weatherproof. Here is the link and the stickers that I ordered. I don't know how long this sale will last. Mods, if there is an issue with me posting this please delete.
