My personal feelings are that unless it directly deals with the event or items to be used at the event, it's commerce. The deal Doc gets for people at the Sands is one of those done for Burners, he doesn't profit from it & doesn't have a connection with the Sands (other than as a customer); I think it passes the "commerce test". The coupon thread is nice for bargain hunting, but doesn't really have any direct connection with the Burn, I'm one of those who counts it as commerce (well meaning, but still commerce)
But the problem is, it did!
The coupon I posted and freebies where all stuff that people have said they use out on the playa- Such as protein bars and free enegery bars. I aksed people to post food coupons for things like pop tarts and other stuff that is used out on the playa. Nothing was said about post your fav frozen food coupon. It was labeled couponing to save money on food for burning man or something along those lines. I wanted only coupons for things that could be used on the playa that we all use there. Please look at the post if it is not totally gone.
I do not have any connections with the site or with the manufacturer, nor do I profit from this.
So honestly how is it different?
Also if you think about it im not persuading people to go out and buy something to. Most of us buy this stuff regardless why not get a deal and do some "winning" so that way you have more money to bring gifts out to the playa. So it's not "Spam" if you buy it anyways from before you got the "spamming"
PS. I started a thread about where to get cheap booze... people have posted links to pages to buy cheap booze... how is that one any diff other then no coupons? People posted links there and on the coupon thread.
