I bought three pairs at $6.50, ea. I got the impression that the vendor is very new at running an ebay auction. You can only bid on one pair, and choose a color after you win the auction. At that point, you can also increase the number that you purchase. We were able to work out the number and colors (yellow, dark green, and light green), but the vendor had some real problems adjusting the invoice to cover three pairs. After numerous emails, the vendor ended up sending a separate invoice for the extra two pairs, and I then received a message from ebay telling me that my purchase had been shipped.
