Thank you very much, littly_kitty. This is just the information I've been looking for. I appreciate the time you took to write it up.

I've been trying like anything to avoid asking yet another stupid question, but I'm stuck. I can't find anywhere that explains how to install a module. I think uc_multi_stock is probably the way to go (though uc_stockstub could probably work equally as well), but I can't find any information on module installation. Am I just not looking in the right places?

Again, thank you very much to everyone here - your helpfulness is GREATLY appreciated.

thanks,
amy
