Stay Away! I sent them two lenses they were going to buy. They lowballed the quote, but I wanted to sell them quickly so I can upgrade. I sent both lenses through a Fed Ex shipping center in the same package. MPB says they received one lens and did not receive the other lens. They have stated it would take two days for an internal investigation. I have called several times and left several messages with no responses. After calling and complaining to an associate I received a phone call from a manager. She stated they had to start an internal investigation again. So they have not even looked at the file. I asked them to send back the lens they are saying they received. DO NOT USE THIS COMPANY!!! We are now going on ten days, and I have not received any solution to them losing my lens.
