Just takes you to their homepage - "www.volusion.co.uk/VSnopCommerce" doesn't seem to be an actual page.
Just noticed this thread, and being in North America, just did a google on nopcommerce. There is a volusion ad, but its different then the screenshot above. It looks to be non negative... just reads "Considering nopCommerce?" and tries to lure the user in. Effectively they are buying the nopcommerce keyword as part of their campaign. 3dcart and avalara are also actively buying the word as part of their adwords.
Thanks for reporting. I'll contact them.
