Literally one of the worst online shopping experiences I've ever had. Was trading my Tamron F2.8 70-200 lens in for the newest version of the same lens. They sent me the exact model back, who knows, maybe it is my lens. I had wanted the lens in time to shoot my daughter's college swim team's upcoming swim meet. When I called them, they promised to overnight the correct lens to me. And that I could send the incorrect one back after I received the new one. The next day, nothing. Next day, nothing. No email notification, nothing. Called them again for the third time this week. Now they're telling me I needed to send the incorrect lens to them before they send me the replacement. They screwed up for a second time. Oh yeah and we are halfway through the meet. I will never purchase anything from them again. Would give negative stars if possible
