When up to 6 stickers are ordered alone, or in combination with a made-to-order item, I will mail your stickers (for free) through standard USPS postal system in a stamped envelope. Unfortunately, this means I do not offer tracking info for these types of orders. If you do not receive your stickers within 7 days, please reach out to me at elissa@elissamariecreative.com. If you order more than 6 stickers, or in combination with in-stock items (notebooks, socks, tote bags), they will all ship together via tracked and insured First Class mail. I appreciate your patience! As I grow and expand my business, I aim to simplify my shipping methods and hold more items in stock.
