Thanks for the workaround, but this should 100% be Shopify's responsbility.
Why for every little tweak to our sites do we have to pay for apps?! Spent the last 2 days trying to automatically apply a discount code and now this.
The shipping solution is interesting but I also want my (25% off a tshirt when you buy x) to stack with my general (10% off shopping cart) codes.
Please shopify... put a tickbox in discounts that says "stacks with other discounts"
Couldn't agree with you more Phil. I remember the days where shopify devs would help out with codes here on the forum...now its just "apps here"..."apps there". Ever since they found out how lucrative apps are (I assume they get a commission on the apps from devs), they decided to make shopify as basic as possible, and make a killing on the apps...in my perception at least.
Sooner or later, this strategy is gonna bite them in the behind.
