I tried Shippingcart by shipping stuff to their Hayward warehouse. Every shipment was processed quickly, shipped and delivered safely. Until they moved the warehouse to Oregon. Many of their customers are complaining that packages are not appearing in their carts, packages not getting shipped, packages that can't be located. Visit the FB page of Shippingcart. Don't ship anything until they get their sh*t together in Oregon. This is a disaster. Should be discussed in business school as an example of poor execution.
April 3,2023 Update:
ShippingCart has not addressed the issues in the Portland, Oregon warehouse. They posted an advisory that the lead time to ship is 35 days. Not true. My package was received by ShippingCart on November 3,2022 and it's not yet in my cart. Contacting ShippingCart by Chat or email is useless. Your tickets get closed as resolved (duh), no results, standard apologetic template email replies, promise to get the warehouse people to prioritize your shipment (they promised everyone). All BS. DO NOT USE THEIR OREGON WAREHOUSE FOR US SHIPMENTS.
Update as of May 12,2023:
Found out today that my access to their FB page was blocked. I guess I have been very critical of their service and it must have affected their revenues. How can you trust a company that messed up, doesn't fix their issues and encourages clients to use their service again. Am going to stay away from them moving forward. Their Oregon warehouse is still a mess. Check the clients posting complaints with shipments stuck for 3 months or more now.
