I tried out the shopping cart. It seams to let me add a pen to the cart, but when I click the "continue shopping" button, it says "Sorry, there are currently no products in this category. Please check back soon." It happens with both pens. But right now, I have both pens in my cart.
The fields to enter my info do come up. One thing I see about that that you might want to think about. The sentence "Shipping Information Click Here to use Billing Iformation. Note: we do not ship to P.O. Boxes. " You might want to consider making this a little bit larger. I missed it the first time I looked at the page.
I filled out the form to contact you through the website. It is titled "Just a test" and sent it. One thing I hate about fields like this is requiring me to add my phone number. Nothing personal, but if I want you to have my number, I'll offer it. I'm using a cell for my main number and I don't want it added to a list. Many times, if a form requires me to add my number and wont let me continue until I do, I'll try to find what I need someplace else. You may want to consider making this an optional field.
Just my opinions. I hope this helps. Best of luck w/ your site
Edit: I forgot to let you know. I'm using Firefox and it shows up fine
