When first trying to buy cards, it can take a while to receive them as you need to give personal information (which takes sometime to be verified). However, it's strictly to make sure the information you use for purchases is legitimate. Once you do that, any subsequent purchases are near instantaneous. Codes typically always arrive in under a minute.
