Zempire tents are on Pricespy so perhaps check the price history there? That model above doesn’t show much movement other than a long term $400 drop a few months back:

normally at the end of tent season(march/april), not the start. 

Stu1: Any reason not interested in the Dwight’s inflatables?. The Zempire ones do look good but normally on sale at end of season

I am looking at purchasing the Snow Peak ecosystem for camping. Their stuff is made in Japan and canvas quality is extremely good and weatherproof. Below model easily accommodates 4 people and is very roomy and breezy for summer camping.

I'd add to the Dwights bandwagon - whilst I don't have one, the kids do.

When they got it and put it up for the first time, there was a tiny hole in the Fly. They contacted Dwights, and they had a new fly on the doorstep in a couple of days. They didn't want the old one back either. That's service, and has gained them a customer for life.

That looks pretty cramped to fit 8 people. Are they going to lie on top of each other ? :)
