I just received my DD's preschool supply list and she needs to bring a different types of stickers to school with her. Where are the best places to purchase inexpensive stickers, either on line or in a store? She needs some seasonal stickers like Autumn, Christmas, etc. as well as a bunch of category stickers like transportation, dinosaurs, etc. I tried to order from Stickersgalore.com and the order process was painful. Would rather not go that route. Thanks!
