Selecting our Standard Shipping (free shipping for orders over $75) service does not guarantee a specific carrier and we cannot choose one for you.
We use a number of different carriers - UPS, FedEx, USPS - if you need a specific carrier (for example if you can only receive packages through a PO Box) you must select that carrier at checkout. Unfortunately, our standard shipping option does not cover this.
