To the Continental USA Only:

We currently offer free shipping on all orders over $299.99 to the lower 48 United States (excludes Alaska and Hawaii.) No code necessary.

If you apply a discount code and your cart total drops under $299, free shipping will not be activated. The total amount AFTER all discounts is what triggers the free shipping.

Exclusions apply. (Some oversize items have a flat-rate fee built in.)
