I am trying to set up:
10 percent of product price discount If ANY of these conditions are TRUE : SKU is one of K27700, K25500, K27950, K14230...
This simply will not apply at checkout with the coupon code set up. It says coupon code is not valid.
Rule is active and applicable to the correct website and customer groups.
Similar coupon works when not restricted to certain SKUs (works site wide).
Can anyone advise if I've set this up wrong?
