The campaign was short, yes, but it was always meant to be just an extremely brief launch offer and not the regular price. Given the quality of our products and materials we use, we really can't sell them any cheaper than we do now. Our products are designed to be the best they can and unfortunately that comes at a price.
Having said that I wouldn't consider the core expensive as such. Keep in mind that unless you enter your location to our store it displays EU pricing by default which includes the Finnish 24% VAT. The US price of the 3 point kit+Core is actually 75.24 USD even without the offer (though some local taxes may apply). At that price you get one of the comfiest and lightest hammocks around which is also really durable due to our own 53g/m2 Ripstop Nylon and the high quality Dyneema suspension.
I can't recall the US shipping price exactly but it's significantly more than 6.40 EUR. The Store does calculate all the prices automatically for you if you add the products to your cart, proceed to checkout and enter your location for it.
This image should illustrate the use of the Tarseer bugnet quite well:

This is the bugnet with our rae tarp:

And if you don't need the bugnet you can let it hang to the sides like this:

The bugnet has two loops on the center zipper, one close to the head end and other closer to the feet, and comes with a long elastic cord attached to the head end loop which you can use to suspend the net. The cord has a small hook at its end for easy operation. Hopefully the images clear it up :)
The Core hammock isn't currently available with the bug net and there are currently no plans to make a bug netted version of it. However we do make custom versions of our products on order ;).
