Site not tested on https://safeweb.norton.com but uses "Norton by symantec" sign

I've found website audiolabcat.lt and considered purchasing from them. They use "norton by symantec" sign, however, https://safeweb.norton.com shows it as not tested. Is this something I should use as an alert? Is it safe to buy from that website or not? The prices there are so appealing that it looks too good to be true :(
