The availability of LEGO Marvel Super Heroes Rocket Raccoon (5002145) at Toys R Us is a bit clearer now. Based on reports and first hand experience, each store is handling it differently.
Based on a computer memo, stores are suppose to hold this set back for a promotion starting on November 21st. However, some stores are ignoring this and stocking the set on shelves or at the customer service counter. If you can’t find it, ask an employee to look up item #084829. If you get your hands on it, there will be no issues purchasing it at the register.
If you can’t find them at Toys R Us, the price has come down a lot on eBay. They’re quite reasonable now with more and more auction listings popping up.
