eBay's policies leave me with no choice but to mark each of my auctions with a “no return” policy. These items are vintage and as much as 35 years old; I bought them over the years and will test them if I have the system to do so. If not, I make that clear in my listings.
This is being stated to protect me against returns such as buyer’s remorse.   After using the item for days and weeks, the buyer can submit a request for return and is not obligated contact the seller first nor to reimburse the seller for return shipping charges; thus, I have to pay for shipping charges back.
Even though an item is marked a “no return,“ a buyer can still submit a return if the item was not as described or the item was damaged during shipping.  The USPS does not accept responsibility for damages above a limit, regardless of any prior extra insurance paid -- I have experienced this twice when sending an Amiga to a buyer.  Keep in mind, that I am retired, living off a limited income and mainly sell vintage Amiga computers and their accessories for extra revenue.
I will work with ALL my customers to resolve the problem when contacted.  Recently, I have had to take back items where the buyer didn’t check with mom/dad/husband/wife/the Lord God prior to buying, and did a return.  A recent buyer said an item didn't work and without contacting me first, returned the item; I immediately provided pictures of it working just as I had listed it. He returned it without asking (how to press a button). Again, eBay forced me to take the item back and charged me for the return shipping.
Personally, I do not think that this is an acceptable way to return items.  Many of the sellers on here increase the item cost or charge twice the shipping to cover this loss.  Sellers here are not Walmart nor Costco and cannot absorb these financial damages.   Again, I will work with all my customers to ensure that they are happy with the item they purchased.  Thank you for your patronage.
