Amazon is discounting The Old Republic inspired set 75001 Republic Troopers vs Sith Troopers down to $9.97 from $12.99 MSRP. Obviously this is in response to Walmart pricing the same set down to the same price. Amazon offers free 2-day shipping with Prime, otherwise you'd need get three to hit the Free Super Saver Shipping threshold of $25 which shouldn't be hard to do since these ARE indeed battle packs. They also do not charge sales tax to most states. Walmart has free in-store pickup or .97 cents delivery to your home but chances are you'll pay tax. Pick your poison.
