Would you sell it on amz on a new account expecting a certain 90 day hold? or would you use an EB/PP account? Personally I'm thinking of an amazon account... and BTW its a server (computer) for sale.
The complete step-by-step guide to get back to selling today!
Quality of buyers is higher on Az than eB so if your item is legit AND matches what Az states for the listing then I would sell it.
BUT KNOW THIS: If even something is WRONG about your item or off compared to the listing and the buyer complains (A-to-Z claim), you WILL be screwed - buyer will keep item and no return for refund - Az will do a force refund. Be aware of that.
Defo go with amazon, they will not give you a 90days if your account is not linked, the worst they will do is suspend your selling privileges for 30days from selling. You stick that on a new eBay account I guarantee it will be suspended without a shadow of a doubt. In terms of safety again I would say amazon is better.
One Item $2,500 Where would you sell it?
