I've only ever bought a cooking set from Ideal World I think. They are still in use (utensils and chinese steaming basket set) and are very good, but to me there is always something a bit tacky about IW. Probably not fair at all of me, but everything seems just a little bit less slick than QVC. Apologies if there are IW fans/workers reading this, I mean no insult! Honest!
The worst customer service I have ever experienced anywhere was Littlewoods online! I bought an outfit for a wedding and in two sizes because I wasn't sure which to pick and when I tried to return the (hooray!) larger one had to endure ten minutes of inquisition before they would let me do it! Sorry to go off topic there, but I always compare CS as QVC with the best and Littlewoods as the worst. IW come somewhere in between!
