Hello, delivery time varies depending on what game products you are looking for. For games like FFXIV and SWTOR, the average delivery time is 15 minutes. For WOW classic and ESO, it's 1-6 hours.
Delivery time depends on how long it takes them to purchase your order from a 3rd party for less money than you paid them. They may repeatedly say "wait just 6 more hours" from Thurs through Saturday before canceling the order because the price of your order keeps increasing.
