I bought this and the price dropped by £30 the next day. The team worded it as 

"From your email I understand that you would like to partial refund due to change price on our website. I can fully understand the disappointment you have experienced as I would feel the same in your situation. Rest assured I will certainly look into your order and I will do my very best to support you."

Having sounded like they were truly eager to help, they then said they confirm the price did go up overnight but they will not be price matching and then warned me that returning may outweigh any price differences. The agent then stopped responding completely.

Completely destroyed my previous great experience with Wayfair, which before today, was considered as a premium retailer. Very disappointed.
