Because I know you were looking for a reason to walk through the doors of your local Walmart during this, the craziest of shopping seasons and here it is. Last night nyjpapi popped into the forum to give a heads up. Apparently these were not located in the LEGO isle, but a large Christmas polybag display (that concept is foreign to me and thus gives me goosebumps) at the front of the store containing bags from multiple themes. YMMY, but good luck and good hunting!
