I am using Dosh for the first time. I had no trouble get the $15 back yesterday from a VGC purchase but today's purchase (more than 24 hours rolling window) has not triggered the $15 cash back. Also, the other thing that is concerning is that the Sams club I visited today does not show up in the nearby locations on Dosh map. On a separate note, like others have mentioned the liquidation of these VGC is a big hit or miss. I was able to liquidate the one I bought today for which I did not get Dosh cash back but the one i bought yesterday I was not able to liquidate it. I even tried buying some groceries using a debit PIN and it did not work.
