While Maplin Electronics is one of my favourite shops, they can be a bit pricey for some items. That �9.99 price, in Chuck's link, is a good example.
The last time I bought a Scart-to-phono lead, the cheapest Curry's could offer was �19.99 (which makes Maplin look cheap!) but I got one in Tesco Extra for �1.97. I think that they've gone up quite a bit in Tesco since then (although they're probably still cheaper than Maplin) but they're often found in 'discount' shops (e.g. places like Poundstretcher) for only a pound or two.
