Wondering if anyone has come across (or created) an app that can handle adding extra shipping costs to a checkout. We have a provider that prints and ships from their location and charges us directly for shipping costs. We want to include this shipping cost in the customers checkout. Essentially, we are fulfilling the customers order from two physical locations.
Customer adds X items from our store that will be fulfilled from print-on-demand service to cart.
Customer also adds X items from our store that will be fulfilled through our normal warehouse to cart.
When customer checks out, app should add extra shipping cost based on preset parameters (customer location + weight + other).
Thanks for any guidance!
