There have been 2 items in the past that I have sold that have been returned to me and in the end I have resold for more to a 2nd buyer. The first one, I had an item that I did not have the means to test, I sold it with a gaurantee to work or return for full refund, the buyer received it it did not work and therfore returned it. I then relisted it as untested for parts or repair and it sold for about $20 more than it did the first time. covered all my original shipping and fees that I lost from the first sell. The second item I also did not have a way to test so I sold it as used. In the description I said untested, not gauranteed to work. The buyer received it and it didn't work therefore he complained, I refused to accept return because it said as-is in listing. He opened a case eBay decided in his favor and forced refund after he returned the item. I then relisted it and instead of used I selected "Not working for parts or repair" and ended up reseliing it for about $5 more than the first time. Second buyer was more than happy with it. Lesson here I learned is that if you don't test it, it is best to select the eBay provided condition "Not working for parts or repair" as I believe I lost the case because it does not matter what the description stated, the conditon I chose was "used" and eBay defines that as a working item.
