I've read the forums and I guess I have a partial answer.
The Group Discount works great, but I need to limit it to certain categories.
i.e, I give customers a 30% discount on certain products, but they are priced at less than $5, so the discount is no big deal to me. But in another category, I have a product that is $200, and 30% is way too much...in fact, I don't even want to discount that product (or category) at all.
Is there anyway we can make it work similar to SaleMaker, which will apply special pricing to certain categories/products.
