Buy this one, couple it with the previous receipt and send both back to the original retailer for a refund.
I got one for the same price from Currys last week as I couldn't get to John Lewis. Very pleased with the sound and build quality. It even comes with both a UK and EU plug which is handy for holidays. Would definitely recommend it.
Got one in July of last year from Amazon for £71
great price...paid 100 quid 3 months ago for these
Great price for these speakers! Love our one.
