What's in a drawer?

Take a look at those pink chests of drawers. They are lovely. And they all look pretty similar to me. Their dimensions match: 73x80x40 for the top one, 73x80x40 for the middle one, 71x81x41 for the bottom one. Now read on for the pricing:

The top one costs £290 at Cox and Cox. The middle one costs £229.00 at Velvet, and the bottom one £275.00 chez Aubergine.

I am well aware of of the free market principles, but I am always amazed when I find big differences between sellers, for one and the same product.
