MoD reader Exokieta15 says his local Wal-Mart has BOHROK for $2.19, BOXORS for $5.00, and EXO-TOA for $15.09. I just stopped by the one near where I work, and they don’t have any 2002 LEGO® sets on sale right now (not that they have much in stock right now), so it sounds like this may be a case of individual stores clearing out old product while others are content to sit on what they’ve got at regular prices.
