As in something for nothing - or almost nothing :)
I went for a info session from a bunch of tourism providers who had grouped together to tell locals about their area.
No hard pressure sales or anything (it really was as advertised) - and they laid on wine & nibbles.
Plus we scored a $100 voucher which we used for a nice hotel.
Cost $0
That's nice :) Although you do need to do something, i.e. go to the info session and listen through the sales talk, so it's more like a reward than freebie to me :)
Most freebies I got were from trade shows but they are mostly trivial stuff like caps, T-shirt, crappy USB keys, etc.
