When I did my gig work, I would often charge based off of what I think I should be paid, but there were times where people didn't like my prices and requested a different deal. If that is the case I often change the totals around and sometimes they accept. Have you ever had to take a lesser deal for any reason? Maybe money is tight and you are okay with a little price drop in order to make the sale. Would you do it? Or do you stick strong on your prices?
