Marsh--I just looked at Quilters-Warehouse and the "discounted" prices they are showing are the same prices that AccuQuilt has. The benefit of buying at AccuQuilt is they have free shipping for $99+ purchases. Buying 3 strip dies at QW would cost over $15 in shipping. AccuQuilt really has an advantage over brick and mortar (where there is sales tax at least) and online sites that justifiably can't afford to offer free shipping.
