in the shopping cart does it show the transit times for the FedEx Smart Post service 2-8 days?
Please expand on your question.
Do you mean, what is posted back from ShipRush, or do you mean what the customer sees during checkout? What eComm solution is this related to?
That is a question for FedEx, or whomever is setting up your FedEx rating in X-Cart. ShipRush is only involved after the sale is done, and the item actually needs to be shipped. We are not involved in the checkout process for rating the shipment or providing x-days of transit time.
