I reserve the right to not pay 3 BTC if I don't use it, however I may choose to still pay you if you've put a lot of work into it.
Check out my thread. Depending on what you want, it might be less than 3 BTC, although you will still have to pay us if you personally decide not to use the logo for whatever reason. We'll work with you until you like the logo (and subsequently want to use the logo), so long as you have an idea of what you want already
