If the item was actually damaged in any way, start a Paypal claim for item not as described. You will get a full refund from the GSP, you  get to keep the item, and the seller does not have to repay the cost of the item.

Just  walking off in a huff won't solve anything. The more it costs Pitney Bowes in refunds, the more likely it is that something will be done to improve the inspection of GSP items.

Not all sellers use GSP, so shop from ones who do not,or ask the seller to opt out before bidding.

Heavy items can be a fair bit cheaper with GSP shipping, but you do have to shop around and consider all aspects.

Just getting huffy never helped anything.
