"Buy two get one free! Mix and match all Transformers, Playskool, Littlest Pet Shop and Thomas the Tank Engine toys."
This is a good opportunity for anyone who still needs to complete their collection....or their holiday shopping list. Or what the heck, toss the freebie into the Toys for Tots bin and give an unfortunate youngster a happy holiday. Who knows, you may be fostering a new fan.
