eBay can provide lots of things for cheaper than buying it elsewhere.
Just be careful if you use PayPal. They charged my account $700 for a transaction I never made. We've had a heck of a time getting that straightened out! The really odd part of it is that they had flagged the transaction as "suspicious" but still tried to get the money out of my account. If we hadn't stopped payment on it (after I spotted it while checking my account online), they would have took it out anyway. I will never use them again & have closed my PayPal account.
