We spent $550 in about 15 minutes (max) when we went last year. Granted, we had to buy an umbrella since it was raining and the two chairs, but also a few hats a polo shirt, my wife got a jacket, I got a 24oz insulated tumbler, ball marker that clips on my hat, badge holders...
It adds up fast. And yes, it was a fast and easy check-out as well. And then we went outside, turned left and went into the shipping area and got everything we didn't need for the day boxed and shipped in under 2 minutes.
