Is it the one that was at the back of iceland store,up from the carpark?
Or is it John Oliver's which is in the main street.
Either way,the bookshop has moved from that back road to Penryn street at the bottom of Redruth,right on the junction at the bottom of Station Hill.
John Oliver is now called something else,the emporium or somesuch i believe,but is still going.
By the sound of things i thinks it's the first one your talking about,their phone number is 01209 211112.Hope this may help.
