I had never heard of wayspa.com before. From what I can see, they seem to deal with true spas only, not one (wo)man shows like many on this board are.
I would say they are more like spabooms sister site, spaemergency. When you visit these two sites, you stay at the site and buy the certificate through the site. You never leave the site unless you click out. With spaboom, the client never goes to the spaboom home page.
