take three terrible stores, mix them together and ....
Dixons/Currys was always a terrible place to buy white goods, tech, etc from.
PC World was always a terrible place to buy PCs and tech from
Carphone Warehouse was a terrible place to buy a phone from (I made that mistake once ... wow was that a bad idea).
Why did anybody, including their own CEO, expect combining the three to produce anything other than a terrible shopping experience?
