Thanks for the replies

And yes, I do have alot of time on my hands! LOL
I was thinking of fixing something with a shopping cart (OS Commerce, zen cart or something similar? Even if it's not free...) I had my consultation with her today, and she really wants a 'Chapters' or 'Amazon' style bookstore, with the same professional look and usability. I was hoping to be able to use MYSQL,
PHP... She currently uses Simply Accounting to scan her items in using a barcode scanner. Is there a way to export that info into something usable? Or do I need to make another database totaly from scratch? We would like it to show the number of items left, and if they are out of stock, etc.
I'm sure I'll have lot's more questions as I go along, but that's enough for now

Thanks in advance for all your help!
