Same old same old. Sorta pointless rapping them on the knuckles once all the stock has been sold.
It'll happen again and again and again.
Remember folks, just like DFS sofas 50% off an artificially high starting price is not a saving in the slightest. Until retailers are stopped from increasing the base price then giving a discount to the "normal" selling price then nothing will change.
Mind you, Debenhams have been caught out by this as no-one shops there at full price anymore, they just wait for a blue cross day and buy it then.
