For tens of thousands of items a single minivend catalog should
be just fine.  Repeat after me, More RAM.

You will need to figure out if you want
Meats -> Fresh
or
Fresh -> Meats

and how you will accomodate that.

You need to give your back end database structures a LOT of
thought.  I doubt there is one way to do it and I doubt there
is any perfect solution.

A shared shopping cart is technologically easy; it is very
difficult politically - eg working with the vendors - and
your user interface will depend heavily on how cooperative
the vendors might be.

minivend is the easy part of this.  ;^)
