For Maplin, this is a good price. I know Lidl have done cheap monitors occasionally but still, £9.99 I think I'll be having one. I'm sure the outlay of £10 will save someone some money, after all a 20 year old fridge can cost £30 to run a month. Yet £200 gets you a new one!... I'll stop babbling...
Can be delivered if you want to avoid the stores, only £2.99 or free if you spend £35+
