Bob Witmer represents an e-fulfillment company. They function as little satellite warehouses that ship out product closer to the receiver than the main warehouse is. It can be a little weird, but Bob Witmer also function similarly for BoardGameGeek.com.
It tends to result in shorter shipment times. For example, my current order is coming from Bob Witmer in Middletown, PA, and was shipped out today and is expected to arrive tomorrow here at my door in Virginia Beach, VA.
I’d be sure to pay attention to shelf-life on a perishable product in case it’s been at the warehouse for a bit.
From what I’ve heard of this particular fulfillment group, they are very poor in any form of communication or responce, but to be fair, you should never need to talk to them or vice versa. If there is an issue, contact the main company (Soylent in this case) instead, if there is an issue.
