Before lots folks get too excited it needs to be pointed out that the £56 delivered is not what they will actually cost.?
There will be 20% VAT on top plus a handling Fee from the shipping company anywhere between £10-20 for the whole shipment. So I reckon they will workout around £68-70 mark.
Still cheaper than from China thru Ebay or Other Uk sources but just not has cheap as many maybe where thinking.???

I'm still game thou.!!
