That GT240 is after a $30 rebate. I'm not sure I'd completely trust rebates for 1/3 of the original price. Newegg does have an XFX GT240 for $60 without any rebates, but it's only DDR3, not GDDR5 like the one advertised.
I jumped on the $10 Dead Space deal. Never played it, but I heard it was really good, and for that price, how could you say no?
