Ffordes t&c says "For UK mainland orders under 2 kg in weight with a value over £50 we would normally use Royal Mail Special Delivery,", which is where the £9.50 comes from. Postage is only £4.25 if you keep the order below £45 (£50?), so you could get 5 rolls with that postage. I see they also have Gold 36exp at £9 a roll, so again you could get 5 rolls delivered for under £50, if that's attractive?
