If the site was an e-commerce from previous owner, then I wouldn't recommend to you as it will be against Registered Mark. Check if the site having any trademarks or not.
I use them as long as they have decent incoming links and they are in the same nicheMuch question is, would purchasing an expired domain for use as a new e-commerce site hold similar value?
Don't overlook the importance of a brand name with e-commerce sites though - an expired domain might look great thanks to its existing backlinks, but if the CTR from Google and subsequent conversion rate is worse because the name doesn't quite match the thing being sold, then it's probably not worth it even if it does rank quicker.
