There is a lot of talk about what you can get in the download center.  Is it all FREE after you purchase?  I am asking because I can't figure out why there is no box for Quantity in the shopping cart.  I can change the quantity in the shopping cart by doing an update shopping cart. Why not have that in the add product and just have a check mark box if someone wants to disable that function for a particular product?

But my main concern is what do I get as far as hacks and modules in the download center and are they free or relatively inexpensive.

Thanks
