An insidious trick many retailers are doing is insisting on SKU's/model #'s unique to their stores. We recently tried to price compare mattresses sold at Sleep Country for example. Good luck. I think its a dirty trick, i.e. the system depends on competition and this is a deliberate attempt to reduce it by obfuscation.
Sleep Country are dirty cheats to begin with...they have sales they won't even tell you about unless you ask for a specific one you saw in an advertisement, not happy with that place at all.
The unique SKU's is common though, Home Depot/Lowes have been doing this for a while on tools especially....hence things like Power Detect and Flexvolt Advantage from Dewalt.
