Hi yes this just happened to me- same name Solly Blessing!
I had a piano listed on Craigslist for 400.00 OBO and he right away offered $450.00 sight unseen and said he'd send a check b/c he was out of the country due to a "lost" in his family!!
the check arrived today for 3,000.00 and I am supposed to send the difference to his "shipper" in Rhode Island who will pick it up.
(I am in New Mexico!) Said to add another $100.00 for my trouble. the check arrived this morning and is on flimsy paper and the signature is "Patti." I called the bank and sent a scanned image to them. beware Solly Blessing and offers that are too good to be true! who buys an old piano sight unseen!!!
