We actually like the imperfections and colour variation, gives it more "character" for lack of a better word. Could be my untrained eye though.
When you say "priced low", what do you consider low? Like $4/sq ft, higher, lower? To be honest, I find this industry very odd, every store has different prices depending on quantity and it's all negotiable (ie. no retail with a discount like other trades). It's very difficult to know what to even negotiate down to.
