Good deals to be had on Nigella Lawson kitchenware, Le Creuset and Brita, to name a few. Some nice artwork in Home Accesories. Plenty of other good deals on home furnishings as well, so have a browse :)
I actually noticed this when looking at picture frames..Tesco's frames are quite reasonably priced and available in sizes not readily available on the cheap elsewhere (e.g. giant 80x60cm and square 40x40cm).
