GameStation are starting this on Friday. Sounds unbelievable, I know, but take in ANY THREE Nintendo DS games on Friday, trade them in and Get Pokemon Platinum for 99p.
Looks to be opening weekend only.
Can only purchase one copy per customer this way and games cannot be duplicates, IE: Can't trade 3 copies of Elite Beat Agents :P.
PS. My local GameStation is not selling any of its £10 or under DS games this weekend, just FYI.
