I told cs-cart that this is a serious oversight or something thought wrong by those who have designed and developed; That's the problem:
we have several conditions to be met, I try to list here to see if you are able to find a solution for us:
1st the VALUE KIT products always free transport
2nd the VALUE KIT products and ORIGINAL products NOT HAVE DISCOUNTS, NEVER
3rd orders over € 25 HAVE free transport
4th orders over € 40 have DISCOUNT 10%
so if there is any product in the basket and a VALUE product KIT ORIGINAL or a 10% discount is applied only to products which are not ORIGINAL VALUE KIT and, for example:
10XT130X VALUE KIT € 32,90 (free transport yes, discount 10% no)
EPTS510B Samsung CLP 510 toner € 75,00 (free transport yes, you save 10%)
Then 75.00 to 7.50 = 67.5
ORDER TOTAL 67.50 + 32.90 = 100.4
apparently this situation it is impossible to cs-cart, since the discount 10% is calculated for all or nothing, have a different solution?
a prize to those who can solve this problem with the standard tools of cs-cart
