Can I pay(Credit Card debts) back the same day?

Hello guys,so I happen to have the interest in buying a gift from one of the electronic stores here in Canada(through online store).Sadly the only method is with a gift card or credit cards which I simply don't have.Well I have cash though but neither of the stores are within my vicinity.So I was wondering if I can go to the bank,take a credit card and repay instantly just to be able to use the Credit card.The store is Future Shop. Any suggestions are welcome.Thanks in advance.
