Some other things to do to protect your credit cards while shopping online include:
- Avoid purchasing any product advertised in spam (unsolicited or "junk" email).
- Minimise potential damages by using a credit card with a low credit limit.
- Never make a purchase on a public computer.
- Keep an email and paper trail of your purchase.
- Act quickly if there is a problem - report the problem to the shop, your credit card company or even the police.
