2. Use Paypal
For those who don’t know, PayPal is a well-known payment service that allows you to open an account, where you only have to enter your credit card number once, and it stays only on the secure PayPal website and is not distributed to other websites.
Most major shopping sites work with this service, which significantly increases your chances of a problem-free purchase. In case of account hacking, God forbid, you can deny the transactions like with the credit companies, and get the money back.
