As an aside: somewhat ironic that a shop selling gear such as this has such a large 3rd-party javascript footprint. At least some of that js is required for the page to work, as I'm unable to see pictures of the device. I counted 25 3rd party domains in uMatrix. That's quite the attack surface.
I bought something from them once, and they shared my email address with Facebook to do targeted advertising - that was not something I expected they would do.
Oh why thank you. Yes, I just landed on your page for the first time, looking around to see what you got there.
What? If only I give you my email adress you will send me info about your page on a weekly basis as if I were the most interested person? And I have no guarantee you wont share my adress further? That sounds like an amazing deal! Let me sign up right now, before I even can read a paragraph on your page, I feel like I will definetly not regret it.

Seriously, how do these modals still have high enough conversion rate to justify their existence?
