Thats odd, ive just done it and it came to a staggering £4.51 inc Delivery I also noticed you changed it so your ordering 187 cables Sam
Not weird, it's in Amazon's T&C. so buyer beware. I've had some great bargains from Marketplace and it's safer than eBay, but I suspect some of these "penny sale" items are bad people trying it on. I've seen quite a lot, especially in books. Other sellers will say the total cost (if you only buy 1 item) is fair, they're tied to Amazon's rate and conditions, so take their profit from the delivery rather than the item price. Reason for 187 was to get an order up to £15.
