Really great advice, Macybaby. My son is an ebay seller with a 3-star rating, and has been years even getting to this point, ebay is hard to deal with (lots of persnickety rules) money problems with PayPal, but he just keeps on keeping on because it is the lesser of the evils out there for selling the merchandise that he spends every Saturday looking for and finding, researching and labeling, pricing, etc. Attempting to sell locally is difficult, too, because the audience you may be dealing with has probably already seen what you have found and now want to sell.
BTW, his latest acquisitions are a Singer 128 in a coffin cover carrier, and a beautiful Kenmore in a 4-legged cabinet and brought them over to me to figure out what to do with them. I had a fit over them, but I have more machines than I have space for anymore--so I am still pondering on that one.
