The thickness in a Jiffy bag would push you into large letter territory. Weight over 250g then £2.05 add in the cost of a Jiffy bag in small quantities you're in 3 quid territory for first class. Where postage is quoted for small vessels it's normally over £3 on the popular auction site. This can add 60% to the purchase price.
