IIRC part of the problem is that merchants don’t necessarily post charges to your account immediately. They place a hold on funds, but it’s not necessarily charged. That’s especially true for buying gas, where the amount you are going to spend isn’t known until after you’re done filling your tank. The way around that is to have to pre-pay for gas.
