For 6 items I got $37.19, but I think that is US postal rates (says first class or priority). I get the feeling they'd send another invoice for postage.
And, unless I'm being stupid, I think the discount (BOGOF) only applies if you buy 2 exactly the same. For instance, I wanted 2 small pockets or wraps, but in different colours and it shows the full price for both, even when I take it through to checkout. If I put 2 of the same colour into my basket, the discount applies
Edited to show postage costs in dollars not pounds, it's not THAT much of a rip-off
