I've seen some cheap prices.
Overall, have people had good or bad experiences with this?
I think most, if not all of us have. eBay has great deals and you will usually find things cheaper on there.
I've bought only two items from eBay, but in both cases were excellent and positive experiences. If you're new to eBay, you should obviously be cautious of who you buy from. Try to buy from top-rated and positive-feedback sellers. The trick when buying is to check the user's feedback.
No problem. Oh and you shouldn't worry too much about scams because you're protected through eBay's protection program. On top of that, you're also protected by Paypal. Most importantly though you should link your credit card with your Paypal account. That way, if eBay or Paypal can't recover your money, you can always issue a chargeback. So you have triple protection, no sweat.
