When buying something online can i use my debit card number even if it only says credit card?

I have a Visa Debit Card. I want to buy some acne medicine online but it only offers credit card type and number can i insert my debit information into the credit card slot?|||Yep. Debt cards with major credit card logos (Visa, Master Card, etc) can be used exactly like a credit card. But if you don't have a credit card account, the transaction will be converted to a debt card transaction and the money will be taken form your checking account immediately.|||Hey, Dan B nailed it!
