If you look at Larry's url you'll see it's a page of deals tailored to him because he has Ozone Adv 10. Hence the lower prices.
It's a publically accessible page though, just as the page offering the $199 Everything Bundle was earlier this year. So they may honour purchases made through this page for everyone, just as they did before, or they may not. I haven't clicked through to see how sketchy things look during checkout.
If you want to be on the extra safe side, go through your account to your own loyalty offers. Or better yet hit the resellers.
Edit: Based on Grem’s last post it’s probably fine. I would happily chance it myself.
