We'll discuss it again. In the past, we haven't allowed this because it turns into a spam-fest with vendors posting advertising for free, or giving a member discounts for posting links for them, etc.
The fundamental nature of HF is non-commercial. We only allow vendors who actually make their products...no resellers. (Stores who buy their products and sell to customers, but don't actually do anything original for the community.) This setup rewards our cottage makers who are actually creating new products and forcing evolution of the hammock camping market, and is neutral towards folks who are just selling a mass-produced product. What you're asking will tip the balance a little more towards the mass-marketers...and kinda goes against the fundamentally non-commercial community we try to cultivate here.
But we'll discuss it and see if it's time to find a new balance.
