Bought one of these the other day via click & collect (no postage costs). They are £34.99 in store but £19.99 if you use click & collect. Not sure if it's a pricing error on the site.
The harness is almost identical to another one I have a Ruffwear Web Master harness which was a lot more money and doesn't include the saddlebags (the saddlebags are detachable by the way).
Very good quality and a bit of a bargain at £19.99.
