A couple of weeks ago there was a local classified ad that had a 2000 mim and cheap amp for $100. In the ad the seller said her BIL had left her the stuff and she just wanted to get rid of it. I responded immediately of course, to a cell phone #, and the seller said she had put the price too low and would repost the ad at a higher price. In 20 minutes the ad was gone; no follow up ad appeared. Then last night there was another ad posted with a different name and cell#, again a woman who this time said her grandma left her an old acoustic guitar. The seller wanted $20 for it. Looking at the sound hole in the pic I saw it was an old Gretsch with a hand written four digit serial number. I was out of town so I didn’t respond but within ten minutes the ad was removed. Are these people scamming?
