I've read a ton of posts on the forums and plenty of reviews of NAHC on external websites, most of them have been fairly negative. However, I feel that some people may be joining the club for the wrong reasons. If you're looking to pay $12/year in order to get a bunch of cool free stuff, whether it's what's advertised or not, sorry folks but you're either naive, ignorant, gullible, or a nasty mix of the three. Very little in life is free, period. I'm not saying misleading advertisements are ok, I'm just saying that it seems not an entirely large amount of people use their brains anymore.
Now, don't get me wrong here, you may have had a horrible experience...but here's what I've seen so far for myself: I'm shipped random books and whatnot to preview, and pay $8 to keep, or return it. To me, that's not so bad, as usually I can spare the money to keep the book, which I may have not "needed" but I can add to my library anyway. The magazine is pretty neat as well. Being a traditional bowhunter, it doesn't appeal as much to me but I still enjoy reading it. As for contests, hey if I win something, awesome, if I don't, it's not like I've lost anything.
Field testing gear is always a cool idea if you've got some spare time, although sometimes the product is a bit tacky (do you really expect someone to send you a $800 bow right away just to try?).
I've read a ton of complaints about folks getting sent to collections for payment of something they were sent and have returned. To me, this is kind of silly. If you keep good records and document what you receive, when you've returned it, or get a post office return slip or something when you go to return the item (be creative if you need to) then you could easily make a pretty good case for yourself.
Anyway, just wanted to be one of the few that have said something positive. I wasn't given incentive to write this, just thought someone would like to hear some feedback that isn't negative.
