(editing as I go through)
Responsiveness is kinda messed up on smaller formats.
Realm select and feedback text go outside the main wrapper.
Make the home page input a true form.
Code:
$(".form).on("submit", function (e) {
e.preventDefault();
})
Should work. Makes it so its a form, but doesnt take you to the action on submit.
It would be more helpful if you made it more apparent that the blue text at the bottom of each item was the seller.
Also, ux idea, sorry I'm just a stickler...What about only listing one instance of each item. For example, there are a few different line items of Fools Cap. Instead, only have one, but make each instance clickable and similar to the way TSM handles it(on click a list drops down of each buyer and the price they're selling at)
