When your pricing page says "10 checks per URL" etc what does it mean? I assume it means that more things are checked as you move up the tiers but I couldn't find any table of what things were checked at what pricepoints. Edit: there's a problem with your payments flow. I signed up, paid, and got another prompt to pay. I reloaded that page and saw that my card was saved, so I hit it again and got another prompt to pay. I signed in using the email confirmation and got a prompt to pay showing my card, which then redirected me /subscriptions which 404s. There's an authorisation sitting on my card for a null amount.
