We've been working with a fulfillment company for a number of years now. Part of our agreement is they get the entire UPS discount and we really don't get charged a pick and pack fee.
On average, we ship 1000 packages per month, and mostly of large sizes, on average, 15 lbs.
What kind of discount would one expect with that kind of volume? I've always sort of based my assumptions on something like a 15% discount for Ground but I'm starting to think my assumptions are a little on the low end.
