TIPS for Buying Online

I don't know what the rest of you do to help ensure online purchasing safety, but here's a few of the things that I do:
1. Any time a site has obvious misspelling or other grammatical errors, I do not order from that site. In my opinion, if they don't have the staffing to have a site that's well kept from the standpoint of English language, then I don't care to do business with them.
2. I always use the same credit card for my online buying for two reasons:
** It helps me see my online purchases on my bill at the end of the month, and scan for debits that might be bogus.
** If anyone gets a credit card number from stealing it online, they will at least get only ONE credit card and not a half dozen.
3. I NEVER NEVER EVER use a debit card online. My stepson had his debit card number stolen that way and had several hundred dollars' worth of charges put on the card before he caught the problem. He got his money back, but it took a couple of weeks.
4. I rarely "set up an account" when offered the opportunity to do so at an online store. But if I do, I don't store my credit card info on their site.
5. If I have an online account, I NEVER use the same password as my online banking account. That's a sure-fire way to ask for trouble.
6. Any time I have a doubt about a new online shopping site, I do a search for the opinions of others who have used the site. If the site gets a uniformly bad rating, then I don't use it.
7. Using Paypal to pay for an online purchase, when the option exists, may be a way to avoid giving your credit card info to online shopping sites, as many do accept Paypal.
