Update
UberRUSH is experiencing an unexpected technical issue. If you've added UberRUSH to a shipping zone, then shipping rates from UberRUSH aren't appearing at checkout. This means that some customers can't complete their purchase.
We recommend that you add rates from another carrier to shipping zones where UberRUSH is active. If there are no carrier services available, add a price-based or weight-based rate.
We'll post an update on this page when UberRUSH is back up and running.
