They're listing sales for Cake Mania, Cooking Mama, The New York Times Crosswords, and Konami Classics for $9.99 each. I've played all four. Konami Classics and NYT Crosswords are great deals and well worth the money if you like old arcade games and crosswords, respectively. Cooking Mama is okay - $10's about the right price for it. And I don't really care about Cake Mania, but my girlfriend won't leave it alone, so your mileage may vary.
Sorry, late to the party on this one. My wife just found out about this game today and we want to see what it's like. Gotta agree, the graphics look pretty terrible, but I can live with that if the exercises are decent.
