Whether you got a good price depends on what part of the country you live in. If you check “sold for” not “asking prices” on eBay in your area you can get an idea what the going rate is, but you also have to take in consideration shipping cost. You can also check Craig’s list and Facebook selling groups in your area for “asking prices”. Thrift stores usually don’t negotiate but antique malls, flea markets, yard sales will sometimes come down on their prices. But you will insult them if you try and low ball them.
