It's not a terrible deal, but it's not exactly a stellar deal either.
To be fair, that is the best summary of this deal and even I will admit it.
The thing that this deal has going for it is quantity, availability and convenience.
It's pretty much the difference between having 3700 MH/s up and mining NOW, vs chasing card deals around for a couple months.
If someone has time to sit and bid every decent deal that comes up on Ebay, then there's a chance they could do better than what I have to offer.
Regardless of card, at 240 BTC on 11 cards, that's a breakdown of 21.82 BTC/card or $111.27 USD per card using $5.10 as the current BTC price.
Buying all of the cards that I have listed here, I very much doubt that someone could average $112 USD SHIPPED, per card over 11 cards if buying everything separately.
