Prices are all on the Seekoutside website. Just click on the product to want and scroll down. Click on the buy now tab to get pricing.
I can say that the price is relative, and is in the middle of the road (price wise) when comparing all the different tipies out there. And if you were just going by information available online, Seekoutside is tops in quality. Only time will tell. If you want good quality, you have to pay for it.
I looked at it from the prospective of buyin a new longbow. I could make one, and it might shoot OK, but I could buy an awesome custom one and have the quality be second to none. I opted not to make my own tipi for obvious reasons, and I wasn't about to spend $200 on a Sportsmen's Guide one and be completely unhappy.
