StarWars.com has a nice article pointing out the special items being offered by Best Buy, Target and Wal*Mart. But what about other retailers?
Suncoast Video - has a special "Star Wars" patch
F.Y.E. Stores - are offering a 15-page Comic Book sized Cover booklet, with cover art by the likes of Drew Struzan and Dave Dorman.
And of course different stores are all having different prices for the film (in both widescreen and full screen), so check your local stores for the lowest price.
