The Lego Harry Potter years 1-4 for Wii or DS is priced at $14.99 today. This is the lowest I have posted this game. You get free shipping on your order- just be sure to select standard shipping at checkout.
You can get the Harry Potter and the Deathly Hallows part 1 for Wii for $19.99 and part 2 is still priced at $49.99.

I paid double for this game at Christmas time. It’s a lot of fun!
