Worst groupon voucher ever was for Discover scuba diving. I spent the next 3 months in the pool with people who didn't even bother to research anything. The result was I had to teach 2 girls how to scuba dive even though they didn't know how to swim, another who didn't bring his swimming costume and a guy who I had to strap 20kgs of lead onto his belt just to get him to sink (needed another 2 to keep him down).
Besides that I've had no issues with them.

Ex colleague used them a few times with mixed results. Personally I have not. Never really considered them. Always a bit worried about getting the goods or services promised.
Only have had good experience with them order last week and they phoned me this morning saying its there and they said delivery is 2-3 weeks.
I bought two courses through them. Microsoft SQL package and Complete web development.
Busy with both at the moment. Had no issues :-)
