hello,
we need to implement discount based on cart quantity items of a specific category.

we want to add products to a "promoção" category (both products have same price 9,5€) if we choose 9 the price will be 9 x 9,5€ if we choose 10 to 14, it will be 10 x 5€, if we chose 15 to 24 it will be 15x 4,7€

we already tried coupon / discount but we can't solve this.

imagine we have 5 items + 5 items of same category it applies the discount..

any idea how to solve this?

thanks in advanced

Dear Philip, thank you

we already tried this it works partial but it only shows the discount after checkout process..

it's not the best solution but we need to have something til the end of the day..


we will test if it Works with many coupons configured.. we need to have:

10 .. 14 items price is 5€ and not 9,5
15 .. 24 items price is 4,7 and note 9,5
25 .. 34 items price is 4,5
35 .. 44 items price is 4€
45.. 149 items price 3,85€
150 or more 2,95€

we have other problem, the total in the checkout sum is not correct but we will debug it today.

thank you

thank you for your sugestion, we tried with coupon but the items with variants are also included and we don't want that.

we will try to change original code to do this:

we are thinking on:

add a field in hikashop_product called grouppromotion, it will assume null or a number, this number identify the group of the promotion.

we need to check on the checkout what items have this field filled and sum them all, and with that sum we can make the apropriate discount, we will have a temp table with the range of discounts.

can you tell us how to grab that information on the checkout ?

thanks in advanced
