Similar situation
Using PS2, eCart 5, php and UPS shipping:
I too have 3 categories. CategoryID 1 and CategoryID 3 are products, CategoryID 2 is replacement parts. The parts vary in size, so we'd like to ship 1-4 parts in one box @ $9.95/box. We'd like to offer flat rate UPS shipping for CategoryID 2. The shipping rules would look like:
CategoryID 2 >=1
AND
CategoryID 2 <=4
Flat rate $9.95
CategoryID 2 >=5
CategoryID 2 <=8
Flat rate $19.00 ...etc.
but I'm banging my head on how to get the CategoryID into the cart? I'm sure it's easier than I'm making it...
