theres a lot of completed sales on ebay for 32gb ipads inthe range of $690-$720 with free shipping if you ask me after ebay and paypal fees there is not much of a profit. others are lucky but some are not.
example: $599 + tax= $640+/- plus ebay $23 final value fee = $663 then you sell it for $700 on ebay. $700-3% paypal fee = $679- free shipping (most of the auction I saw had free shipping) lets say the sale was international, shipping is about $25 minimum, $679-$25= $654.00
You paid $640 for the ipad, you sold it for $700 on ebay after fees and shipping you end up with a $14.00 profit and if you drove to the post office with the gas prices right now lets say you used $4.00 of gas. You end up with a cool profit of $10.00
Not worth it unless youre lucky, iphone sales are another story, I do make huge profit out of them
