About the delivery time...it took 2 hours. I was about to starve. I was pretty patient about it. I got really hungry and called the place about an hour and a half into the wait...but just to make sure my online order was processed. My girlfriend on the other hand...wasn't patient. Kept telling me every 10 minutes that I should get my money back. But she's a redhead...and has a short temper.
