Q: How can I add a multi-pack item into my Informed.co formula?
A: You'll need to click edit on your item in sku grid and scroll down. Click Override Default Selling Formula and then when the wizard opens, close it. Then in the selling formula box on that individual item just type (vendor_price*2) if you're only looking to send just the supplier price x 2. Or you could do the following:
(vendor_price+vendor_shipping)*2 -- if you also need to double the shipping
Or
(vendor_price*2)+vendor_shipping --- if you only want to double the vendor price and send shipping once. This formula would apply only to the 1 item while the other items are using your default formula.
Note: You'd need to give about an hour for the new information to be sent through on the informed CSV link.
