Thanks mate.
Popped into my local TRU after work today. The Marvel banner I wanted was sold earlier today. But I got the other Marvel banner. $150 less 25% off. Sweeeet.
EDIT: I nearly took home the MLP banner... for my niece. Nearly...
Lego banners had the 'Not for sale' sign. Looks as though Lego doesn't want their displays in other people's hands.
