Was in the market for a new seat and saw them for £28 at Amazon and £25 (oos) - £40 @ B&Q but Homebase (and Argos) have these fairly Bog-Standard offers. fnar fnar
Loads instock in my local or delivery for the £14.99 one
There is a Plastic Anti-bacterial Soft Close one for £14.99 which I reserved but after viewing, I opted to buy the dearer MDF one @£17.49 which has some sort of plastic shiny coating on & seemed much stronger/sturdier for a chap like me. the plastic one would be fine for most of you lightweights.
There is a Natural Oak one @ Homebase for £19.99, If you prefer a bit of wood, or see Argos as they have a pine one for £14.99
