Ah, ok.
You mean the £349 (+ £20 delivery) ones from that dealer that 'True Blue' used?
Don't worry. If that was the seller you meant, then at least you got a full 12 months guarantee for your extra money and £349 is still a good deal. (And you got a choice of finishes - if it is the same one I remember.)
Mine were £399 last year (ex-dem from a local Rega dealer) when the R3's were still 'current range' and retailed for £498
