Our basic Tesco manual microwave went bust yesterday so was searching for microwave deals. Searched for microwaves on the Asda George site and in the search listings it was showing Russell Hobbs RHM1709 starting from £24.98 but when clicked on the link it showed only cream color for £42. Obviously the ones priced £24.98 which were Black and Silver had gone OOS online.
Having seen in store the same microwaves priced for £37, I went and asked for a price check on the black model marked with a sticker of £37 in sale. And voila, it scanned at £24.98!!!
Bought 2, one for us and one for the in-laws. No blacks ones left but there were still about 6 silver ones in ASDA Feltham. Hope this helps someone. Note that it is a very basic 17L 700W microwave but it was just what we were looking for.
