StickerMule is super easy to work with, I love that they send you proofs to review before you place the order and sometimes they even suggest changes to your sizing to give you the best product for your needs. I have definitely made stickers too small and too big. Its also really handy that you can reorder previous orders saved in your profile, that way I don't have to go through the sizing process, I already know it will be right. Prices are good and shipping is fast, I have zero complaints with their service!
