Jan, I get my vinyl on line from Expressions Vinyl. There are a couple of sites that evaluate the different cutting machine but this is the one I like--- Silhouette School--- an excellent site for tutorials and info.
Scrapbook store does this often. If you go to their site there is a thread that has all of the different giveaways you can enter. Really nice! I think I entered one for something....don't remember what so I guess I didn't win!
