I think you need to do something along the lines of how the DVD got added.

For it to say if the total is less than 100 to delete the DVD from the Cart.

How you would implement this, you will have to look at the functions that take place you manually delete a product from the Cart.

Well that's how I'd start to work it out. It does sound as though it should be fairly simple to do.

Hope it helps.
