I presume the sale is not retroactive like that. Wouldn't surprise me. This entire deal wasn't thought out well 'at all'. But, this is likely aimed at the very small vector of the gaming crowd that somehow either is just starting to play this game, and/or needs Logitech equipment, or that are thinking of getting into STO, and 'somehow' sees this offer as an extra incentive.
In other words... one freaking small demographic this is aimed at. Again, not well thought out, too much of a stretch.
