you didn't ask for the website to be reviewed but here we go:
The registration page (Next Step) link should show an error showing that you need to make at least one selection. It looks like you are trying to use javascript for this (said trying because it doesn't work).
for
SEO purposes you should try to avoid being able to browse your website without www.
you use https:// everywhere now, which will stop your website from being indexed properly also an
SEO issue
alt tags for the features images should be more to the point not just "promo image" which doesn't make sense and has no connection with what you sell. I would spread the features on few pages instead of scrolling down.
website very slow, seems is waitting for something to load at the bottom of the page, where BTW the </html> closing tag is missing.
and of course all of the above that blacknight mentioned.
