I bought several items through Greentoe bidding and all purchasing went fairly well until the last one. I placed a bid for Tamron 28-75mm f/2.8 and and the offer accepted for $779 by Cardinal camera on October 9th, and the item wasn’t shipped for 2 days so I contacted Greentoe and they said it is back ordered and will cancel and refund the money. Greentoe was able to find another deal through Beach camera and I got the item about a week ago. Meanwhile I contacted Greentoe at least 4 times for the refund from Cardinal camera and as of today haven’t received it and 3 promised refund dates passed by. So, I filed a dispute today through my Credit card company and dealing with it. I still like to get deals through Greentoe but scared use them if they have sellers like this. Greentoe, please remove this seller from your approved sellers.
