I wondered how this works in reality? If I wanted swap something and get something in return, how do you do it, do you wait till you get the other item or do you send them at the same time
and I dont suppose there is any guarentees with this....
Also what if a phone, was security can I take to make sure that they dont say its not working and send me a duff one back in the post? is the IMEI number alone enough?
Thanks for help?
