An actual credit card or a debit / prepaid card? I ask because there is a difference and a lot of online businesses have systems set up that will not accept debit / prepaid cards. Years ago when some of these smaller retailers (vape shops) were having their systems hacked and credit card info compromised/stolen semi-regularly I switched to strictly using a debit/prepaid card for all online purchases (or paypal) and have run across several retailers that do not accept them, even some very large retailers.
