buy from cat A get 10% discount buy from A+b get 15%

hi i have to create this coupon:

if you buy min 50€ from cat A you get 10% discount

if you buy min 100€ from cat A+cat B (global 100€) you get 15% discount

i seem to be not able to do this..

can you help please?

thank you

Hello,
If I understand correctly, you can.

if you buy min 50€ from cat A you get 10% discount:
 Type: coupon
 Value: 10%
 Minimum amount: 50 specific
 Discount type: overall
 Product: add category A

if you buy min 100€ from cat A+cat B (global 100€) you get 15% discount, more or less the same:
 Type: coupon
 Value: 15%
 Minimum amount: 100 specific
 Discount type: overall
 Product: add categories A and B

no. it does not work:

if you buy min 100€ from cat A+cat B (global 100€) you get 15% discount, more or less the same:
 Type: coupon
 Value: 15%
 Minimum amount: 100 specific
 Discount type: overall
 Product: add categories A and B

if the customer adds only products from ONE category has the discount! he should have the discount buying from both..not only one of them

I do not understand, what is the issue?

the buyer have to buy something from each category and not only from one, to have the 15%discount. i can't achieve this..

You can use a parent coupon to achieve this:

coupon A: product specific for category A discount value of 0
coupon B: product specific for category B discount value of 0
coupon C: product specific for category A and B discount value of 0 minimum value specific 100
coupon D: discount value of 15%
coupon E: parent coupon, add coupons A, B, C, D and set process type to ONLY if all apply
