Frequently asked questions
+Is reclaimed always cheaper than new in Chester?
Almost always for standard grades. Premium heritage grades can approach or exceed new prices when new equivalents don't exist.

+Does reclaimed void manufacturer warranties?
New warranties don't apply. Ex-display and surplus stock retains full warranty when unregistered.
