We finally replaced our toaster - a wedding present, so 1981 vintage (Ben asked for it! Sometimes it's really hard to ditch everything you've grown up with) and our microwave oven that was old fashioned even we bought it used 20 years ago.
Mr. Tesco provided a set of vouchers on a £2 for £1 coupon basis. The microwave itself was one of their own designs with 1 knob for setting power levels and 1 knob for time. Perfect. And when we looked more closely at the higher end units we found that they were based on EXACTLY the same steel box and door, but with different control panels and badges. Power levels etc were similar, so we seem to have got essentially the same cooking ability as a £70 microwave for £33.
I'm starting to wonder about a replacement mower under the same scheme!
