Partial Delivery

I got a call from Baxter telling me that my shipment will be split. This was followed by five emails from UPS notifying me of an impending delivery. I checked the details and each box is about 29 lbs. It’s likely boxes of 3L or 6L solution. There are still 30+ boxes in this month’s order so not sure why the split delivery. Maybe they stock different solutions in different warehouses.
