Thank you for the online helper tool showing a perimeter safety zone and screw holes. I was confused when the discount was not applied equally across browsers (I began the cart in Chrome Canary, but clicked the please-come-back link in Mozilla Firefox). And I was frustrated that the paypal option was not working at all (evidently they changed their captcha JS so it force-refreshes my captcha multiple times per second and there is no possible way to load that stupid test, let alone pass it) but I paid via credit card and it seems to have placed the order OK. I appreciated that it offered me a free rush on the shipping because I was not expecting an extra $10 at that point. The whole point of this order was for me to be able to compare with and without your special coating.
