I set up a 37 box shipment using the ShipStation UPS integration (which goes through Stamps.com). $833. For some reason UPS billed an adjustment for a second box on the same package sending my stamps.com balance way negative. It’s been 3-4 days and it hasn’t been resolved yet and I couldn’t use my accounts without paying the balance. I’ve contacted support at all three companies and haven’t gotten a resolution, lots of finger pointing at the others though.
Long story short, I’ll be breaking large shipments up into small ones going forward.
