> ... would this be seen as them paying for this feature? I can't give you an answer that I know is 100% correct and back it up with a primary source. However, I believe that it would be and let me explain why. I recently received a renewal notice in the mail for an organization of which I am a member. A while back I had already decided that when renewal time came around, I would become a "life member". In the marketings materials with the renewal letter was an offer for a slight discount on a lifetime membership along with the option to receive a "free gift" (of my choosing, out of three or four choices) or to forego the "free gift" entirely. If I did not select a free gift, 100% of my membership would be tax-deductible. If I did choose one of the gifts, part of the membership fee would be applied towards that gift and only the remaining amount would be tax-deductible. It's a slightly different situation, obviously, but I believe the decision of whether they are paying or not paying (legally, at least, in the USA), would hinge on whether or not the "donator" was receiving ANY "compensation" -- regardless of what that compensation is.
