Purchased as a bit of fun for a relative's birthday but found that they needed a king size instead of the double  I ordered.  I telephoned Wayfair and expected them to  organise return, refund and replace with the new size ordered without additional delivery charges.  It has cost me £9.98  in delivery charges and I had to drive across town to find a Hermes drop off shop.  I feel really cross about it.  If I find there is a problem with the quality or fit I will donate to charity.  I won't use Wayfair again.  I'm sure it is all in the terms and conditions but life is too short.
