I bought 100% organic bamboo sheet sets on Groupon that turned out to be 0% anything organic about them. In fact they were 100% polyester. When I went to return them, since it took over 30 days to deliver them, it was too late for a refund. So instead I'm supposed to get groupon bucks. Well now it's over 30 days again since I returned them with no actual return seeming to happen. It's just stuck enroute. And what really pisses me off is the same lieing crappy sheet company is still on groupon advertising their polyester sheets as organic! I would include picture of the ad, but don't know how to do phone screen shot " intentionally" ( happens by accident all the time, lol).
