I'd like to do a buy one get one discount for the month of december as well as a % off for a special event. Is there any way that I can do both of these at the same time?
Welcome to the Shopify Community! Simply put, through the natural Shopify settings it's not possible for a customer to use more than one discount in any given order. I understand that offering your customers multiple discounts can be important, especially in big sale periods. So, I've gone ahead and submitted some feedback on your behalf to our developers about requesting this feature for the future. While I can't guarantee any changes, the more feedback we receive, the better!
That being said, in order to offer more than one discount to a customer in a single order, you have a couple options:
If you decide to go with the first option (using the compare at feature) I'd recommend using the Bulk Editor to make the changes, since this will be the fastest way to change the pricing on multiple products.
Let us know how this goes and if you have any other questions!
You can consider using my bundle app, BYOB. We support creating bundle discounts like buying any n products in a collection, getting a discounted price. Since our app is generating dummy variants to adjust prices, we can support additional discount code / auto discount.
Currently, there are more than 10,000 orders generated by our merchants and 50 - 60% of them are stacking discounts. So I guess it's quite effective
