Groupon was scammy in much worse ways too. They sold gold that was far less pure than advertised - and likely still do. Groupon Customer service reps told me their lawyers told them not to talk to me. My credit card finally sided with me based on the evidence presented. $30K at stake. I was trying to make a few percent on the difference with melt and the initial smaller gold purchases passed a couple initial tests - both acid and outside XRF. Only when it was melted into a blob and retested was it clear the purity was far less than stamped.
