I popped into Tesco in Perry Barr a little while ago and spotted this Tesco branded DAB alarm clock for £6 on the SEL. I found it on the a Tesco website and its £24 on there. It's not a local reduction as it didn't have a Reduced To Clear or one of those yellow stickers. Might be worth a look if you're passing by and you're in the market for one (don't go on a wild goose chase!)
The reviews look decent and subjectively the sound is decent considering its a single speaker jobbie, like most alarm clocks are.
