As a seller I find the Ioffer site SLOW, buggy and a major pain in the arse when it comes to updating your items. They have the item grabber thing but it will only grab items that it has NOT grabbed before.
I got over charged for the sale of an item TWICE and I found contacting the admins of that site a nightmare at best, I never did get a reply from ANYONE, ever!
if you only have 1 or 2 items for sale Ioffer would be a good site, but if you have hundreds of items to offer maintain and update the site is a nightmare at best. Time is money and Ioffer is a major time waster for larger seller. Ioffer might make a good toy for some kid but as a real market place it SUCKS in my book!
I joined Ioffer almost 2 years ago and within 2 months stop using the site. I just returned today to check out any improvements they might have made. I am sorry to say I am very disappointed at what I found!
