To keep things simple and fair for everyone, we require a minimum $5 upload to your Stored Funds wallet. Each card transaction has fixed processing costs, which can make very small transactions (like $1 or $2) expensive to handle. Rather than passing those fees to guests as surcharges on small purchases, we chose to set a $5 minimum so you keep full purchasing power and avoid extra charges. Your funds always belong to you – they never expire, and can be refunded at any time.
