Query: A Review of the Vendor

This review is for Adorama, the Amazon vendor who shipped the lens ordered here. The lens sent is NOT a medium sized lens, but is clearly marked Small. It will NOT fit a flip camera. Adorama refused to acknowlege error, and not only refused to refund my initial shipping charges, but said I must pay to have item shipped back if I wanted any credit at all. $15 in shipping costs for a 2" lens which was a mistake is not acceptable. I've done business with Amazon.com for several years, but will be careful NOT to order from any of 3rd party vendors again. If it doesn't come from Amazon, I won't be buying it.
