The last dozen sales, I take pics of how the items are packed, serial #’s, outside pics of the boxes, and a short video of the piece playing. I always send with insurance and adult signature required. I always send the pics and short videos to the buyer and he has to agree he is ok with everything. These procedures have saved me numerous times: buyer said he never received the item but I checked and the shipper had his signature, somebody tried to state the vintage piece didn’t work and he was going to do a swap with his non-working piece so when I told him I will only take it back if the serial #’s matched, he decided to keep it, and a few other instances. These all used PayPal. I’m selling a 150lb turntable now and will only sell it locally after the person hears it and pays cash. Sold a pair of 140lb Ushers that were in perfect shape with boxes and I refused to ship. The guy drove 1000 miles round trip to pick them up. Doing it this way both parties know what they are getting with no surprises.
