Sorry if I'm throwing a spanner in the works here, but are these not the same bags as found on ebay (eg item number 120269792425).
From all the pictures and descriptions they appear to be very similar, and the ones on ebay are available for just under £9.00 each including shipping.
There are the 3 colours listed here plus a number of different camoflaged alternatives.
I've no link to the seller other than to have purchased one of their other bags in the past which was reasonable quality & build for the price.
I hope this is helpful and if it is the same item it saves you all some pennies.
Edit: This is no reflection on the offer made by Rapidboy (I can't compare source or product quality), simply sharing a deal on a similar item.
