Allowing vouchers to discount certain items, when other discounted items are in the cart also

[brandonc503]

id like to sell a chair for $200 on the site, and have a voucher for $75 to that one item in its own category.. but when i have a second item in cart that has say a 10% discount, it wont let me use the voucher?

i know its cause i had the do not use with other discounts, but i figured that would not be a problem if it was in its own category.. any help, ideas, workarounds.. thanks

well,

I tested this and this is working.

I made a voucher of 75 euro on a level 3 subcategory, like test1
then I made a second voucher with 10% discount on the same level 3 subcategory, test2
don't forget to check the options :
in combination with other vouchers
and
in combination with other discounts

look at my screenshot, no problem.
the first voucher -75 euro
the second - 15.9 euro

then only problem I see is a miscalculation!
I have a total amount of 159 euro.
so before given percentage discount you must first remove Valuta discounts :
so 159-75=84 euro
and then -10% = 75.6
+12 euro shipment = 87.6 euro.

why give a person a 10% discount when he didn't pay for total amount.
so this could be a bug???

so look well I miss, 7.6 euro...if you count with large amounts, you lose even more.

did you have that voucher set Cumulative with price reductions?

[deech123]

first voucher = 75 euro reduction
second voucher = 10% reduction.

and I did set this option cumulative with price reductions.
otherwise this can't work.

but be aware that you will give 10% reduction on the full amount...and that's not correct.
prestashop must take the (total - euro reduction) - 10%
