I just wanted to say that yours is the first product that I've tested so far that hasn't failed on handling uploads.  This is going to work for a print company, so they are handling nothing but large files and all the other solutions I've tried so far have not been reliable.  So far yours has been 100% successful in my tests.

Do you know how rare it is to have a "canned" shopping cart that can easily do complex pricing options on a single item?  Basically, they don't exist!  I have looked.  Everywhere!  And the few that might even come close to CornerStore's functionality cost a fortune!

FileChucker is working great...  Clients love it.  Vendors love it.  We love it.
