Shipbob is probably the most frustrating company to work with that I have done business with. Their shipping prices are high, and nobody has the authority to make a decision. After using them for about 5 months, I decided to move my inventory to Amazon at the end of November.
After creating my order to send to Amazon, I found it was too much to send all at once. Shipbob literally held my inventory for more than 30 days (effectively shutting down my store) before sending a partial order to Amazon, and we had more than 100 emails back and forth to get that done!!!
Than to get a simple prepaid UPS order of 14 cases sent to Amazon. It took over a week for them to get the shipment out.
Now, four months after starting this process, I have finally gotten my inventory out and a $2,000+ refund for their overcharges. Don't walk away - Run!!!
Ah, just wait until you see what Amazon will charge you. There are horror stories.
