Nobody likes paying for postage but you either sneak it in to the price (ebay) or get someone else to pay for it (Amazon) or you are straight up with your customers and add it to checkout (Us). We only charge £6 for UK postage and offered free postage above £50 but have now permanently reduced it to £30! Bargain!
Oh and we have added subscription offers on most of our products as well so you can get a permanent10% off all the products you use the most.
