Thanks very much for the suggestions, Kyle!    : )

Sure!  I never stopped to think about it.

On this particular cart the quantity on hand will never exceed 5 or 6, but
I'm sure glad to have the code!  (Perl is VERY new to me.   : )

That's exactly what we've done.
[if data inventory::qty::[item-code] < 1]
SOLD OUT
[else]
<A HREF="[area order [item-code]]" CLASS="buybtn">
PLACE ORDER</A>
[/else]
[/if]  (we'll "pretty it up" later)

Hmmm...  We're not allowing visitors to save orders for checkout later. 
With that disabled, I don't believe that minivend will allow quantity
accumulations.
