I want to buy his item but I don’t have a credit card

Greetings from Dennis

Go to the store and buy a VISA debit card, or VISA gift card.

It will be the same as a credit card but only have a fixed value.
(whatever amount you paid, $10, $15, $30, $50, etc…)

Then you can purchase online without fear of being stolen as you would a regular credit card.
