Hi Virgil,
We went with the order discount method at first - but as we're talking around 70 products, we just get an 'input string was over maximum length (1000)'.
The categories might be a workaround for the above, and makes sense.
On thing I'm struggling with is finding proper documentation on K# and macros in 8.2?
I'm going to sound old now, but found the Developers Guice PDF on Kentico 4 and below much easier to find!
Thanks...
