Their return policy is absolutely horrible.
I ordered a Sigma lens with a Canon mount but somehow the system changed it to a Pentex mount. I even went back to my email and clicked on the link I bought it from and it was a Canon mount.
I called about the return. They require you to pay shipping to get the camera back.
Here is the kicker: they will charge you their part of the "free shipping" when the refund you the price of the item. So the list price is $630 with free shipping but you only get back $622 because they recoup the shipping charge.
This is absurd. I rarely say anything negative about a company but this is absolutely ridiculous.
