don't use your credit card to buy unless you really really trust the large web protected company you are dealing with.
best is to use a transfer or check or paypal
credit cards are not protected transfer . if there is enough money in your account then the hacker./ abuser
can charge all they want if they have your number information . and especially if they have don't previous transactions .. woo hoo now we are cookin.
i only use paypal it uses bank transfers of which i can stop at my bank or use paypal to stop the transfer . no matter the reason.
and there is no stop payment charge either like with a check.
i will keep this short so it will sink in.
