Yep, saw GoHastings doing the last week. Why they price it so all over the place is anyone's guess.
That said, I did snag the Eruptor/ChopChop/Bash tri-pack from them a couple weeks ago for $19.99, then added some filler games and accessories to hit $40 during their free shipping sale.
So...just keep an eye out. Something may still pop in at MSRP from time-to-time.
