I am an e-bay girl! Forget about any other buy sites, I am e-bay only and all-ways! I find EVERYTHING I want and need on their site! E-Bay ALL THE WAAAAY!
When I buy on e-bay, and I am unhappy, I will take detailed pictures and send it back AT MY EXPENSE right away, and let PayPal know right away with a USPS Tracking number on it.
If I sell something on e-bay BE SURE TO TAKE DETAILED PICTURES OF IT IN EVERY WAY so in CASE you get something back that has been switched out, you can prove with your pictures that what you sent out was NOT what was returned. ALL-WAYS protect yourselves with pictures and proof because the scams out there are rampant and you don't want a bad experience as e-bay goes with who has more legitimate proof to prove the truth. Don't be lazy in buying or selling. Take lots of pictures, model numbers, all around, make notes and always have a USPS Tracking number to prove your integrity. Then you will be okay. E-bay cares. You just can't be careless if you want to be listened to and believed by e-bay. They deal with a lot of claims and scams. Make it easy for them and you WILL win, and always tell the truth.
