Group buys are not to be mentioned here by forum rules. Please edit or delete all post referencing them in any way. We don't want another deals thread closed due to rule violations!
How is Groupon a "group buy"? The link was for a single purchase.
You can argue the merits with the mods. I'm simply telling you what their rule is (e.g. Groupon is a group buy to them) and failure to abide by said rules have cost us more than one deals thread on this forum.
