Antique Cupboard Sterling Matching

I wanted to sell 26 pieces of Dolores by Shreve sterling silver flatware. I used this company’s website form to request a quote from them regarding how much they would pay me. They wrote back offering me $ 297 for the 26 pieces. I decided to check online to see what my silver pattern was selling for, and I turned up listings on both eBay and Bonanza, where this company, Antique Cupboard, was offering ONE Dolores by Shreve dinner fork for $ 129.00 OBO. I am frankly taken aback by what I see as serious gouging of the customer. The discrepancy between what they offered to pay me for 26 pieces and what they would charge me to buy 1 piece is so huge as to seem unethical to me. I would NOT do business with this outfit, EVER.
