A flat shipping rate is a guess. Light orders overpay and walk away; heavy ones to the far coast cost you more than you charged.
WP EasyCart PRO asks the carrier instead. At checkout it sends the cart, the shopper’s address and your ship-from code, and shows the prices that come back. USPS, UPS and FedEx are built in, with DHL, Canada Post, Australia Post and Royal Mail beside them. USPS is one switch and your ZIP code: no keys, no developer account.
Real rates. Your names. Your rules.
Every service you offer is a row you control. Shown to shoppers as sets the name at checkout, like “Priority ( 1–3 days )”. Fixed price swaps the quote for your own amount when you want to round it or absorb some of the cost. Free shipping at makes one service free over a cart total, so Ground can be free over your threshold while Express still pays its way. Zone limits a service to the places it makes sense. Drag the rows into the order you want.
Keep it to three or four services that clearly differ in speed and price; that converts better than a wall of look-alikes. Switch on Show estimated delivery days and shoppers see the carrier’s transit estimate next to each rate. Give every product a weight and size, and the quote matches the parcel.
