Hello, I’m currently having a little issue.
My website (orathepeople.com) sells clothing (mainly t-shirts and hoodies) with a print-on-demand method—the customer orders and the facility prints the garment, then ships it.
Recently I’ve started using a mixed offer from 2 different facilities and here’s the issue: the system doesn’t unify the shipping rate. Basically, if I order ITEM A from Facility 1 and ITEM B from Facility 2, I’ll pay 18€ (9€ per shipment) instead of 9€ altogether as I’d wish and set up.
Anyone has any idea on how I could fix this in settings?
