You know, as awesome as that 1/2 Off win was, the show just seems imbalanced when you have $100,000 in one game, a BMW in the showcase, and the rest of the show pretty much as normal. Meanwhile, you've got "BIG MONEY WEEK" and falling money on Door #4 throughout the entire show. Even with a win, it's easy to forget that it is Big Money Week.
Speaking of which, that was a really underwhelming celebration for a $100,000 win. Pay the Rent's win last year was awesome, but I think that's because it's what a normal Pay the Rent win looks like. This needed clangers, or confetti, or something. It was basically 1/2 Off with an extra zero in the graphic.
I'm no expert in lineup building (if you don't believe me, go back and find my HYOs), but I feel like 1/2 Off and Stack the Deck conflict pretty badly.
