With the recent lunar eclipse and my very high-resolution montage, I got a lot of people asking me today on campus if I was selling them and for how much. Since these are people who I don't want to be seen as money-grubbing and since I wasn't *really* planning on selling this and many live paycheck-to-paycheck (admin assistants and poor grad students), I told 'em I would charge $5 for a 12"x18" since my cost is $2.99+tax. So I was at the planetarium today and a thought occurred to me: Perhaps they could sell 20"x30" prints of the eclipse along with their other posters. I talked with one of the people who worked there and she seemed pretty agreeable. I said I could get the 20x30 prints for $10 plus shipping ($4.99 for first, $0.79 for additional, so if they ordered 5 it would be $11.78 average per). I suggested selling them at maybe $20 since their posters go for $10-25. I told 'em I'd split the profits 50/50. Okay, so now I realize there's a lot to actually consider in this. Tax for one thing. Another thing is do I pay for this out of pocket and hope they sell and then they cut me a check for the price plus $4.11 each time one sells, or should they buy them outright from me for $11.78+$4.11 with some sort of buyback agreement on my part if they don't sell? Granted I can't really go back too much on what I already said (so splitting profits 50/50 and *around* a $20 price point), but I'd like to know what's normally done in these situations, please!
