Just got Beatles for 360 in NYC for $18.50 after tax. Used the 15% coupon. The titles won't ring up as 20, but they had a LITTLE paper sign on the Rock Band display that said 19.99.
Also, didn't print out the coupon, just told the cashier the number 15PRCNTOFF.
All Beatles, RB2 and RB where on sale for $19.99. They did not have any Lego RB, nor did they have a sign mentioning Lego was on sale.
Thanks, OP.
