This is how I stay safe when buying anything online.
1 find out what the total amount of your purchase will be, including tax, and shipping.
2 go to your bank, and get a Visa gift card in that exact amount.
3 use the gift card for your purchase
4 throw card away afterwards.
There is no more money on the card, so even if someone does get the info about the card np there is no money on it anyway.
Gift cards are only $3 dollars USA. A cheap price to pay to know you are safe.
1. get credit card
2. watch credit card statement online
3. If anything happens call and get a new card no problem.
