I think the $40 MP-Skywarp was an online-only offer.
Heck! They've upped it to $50 now online-only, too.
btw, for Silverbolt, I was actually just price-checking it since I thought it was put there in the bargain-aisle by mistake. Well, turns out it wasn't a mistake.
In contrast, there's a bunch of ROTF-figures in the $10 bargain-aisle, which I think is a huge mistake as these figures are really worth no more than $5.
Also, kinda weird that Red Powerglide went up to $30 again after being discounted to $25 just last month.
edit:
just couldn't resist gerwalkin' SB. he's actually got surprisingly good balance. prolly better gerwalkin' than the Bandai DX VF25s.
