I have placed an order with an online store which preauthorises charges at 100% the price of the item. Now on my Visa Electron debit card I have a daily purchase limit of say x dollars. The purchase exceeded the limit by y dollars. I spoke with the bank to raise the limit enough to cover the $y purchase and the transaction must have been preauthorised successfully because I received a notification SMS from my bank.
My question is that since the limit will be lowered to $x within a few minutes, and the completion of the transaction will happen any time during the coming week, will the transaction definitely pass since it was preauthorised, or can it fail again due to the exceeded limit?
