I figure you can take the burden off of yourself:
State the terms that anyone ordering is responsible for 100% of their payment AS A DEPOSIT. Then when the final charges are made (with the +/- 10%) people can pay any additional funds + shipping or forfeit their 'deposit'. People can take one last time to adjust their orders if need be. I'm ok with the 10% variance. If there's a chance of getting 10% more, I might adjust my order from 100 to 90 to compensate.
