A: No! I have a minimum order quantity to contend with and currently have 50 of each dog sticker, for example. I can't do custom orders or make more versions because it's not financially feasible. If you want to order 50 of one kind of dog, I may be willing to help you with that (would include manufacturing costs + custom art commission labor costs)!
