$400 is low and $175 is ridiculous (unless your cake is a sloppy mess) Setting out to put real bakeries and people who don't want to work for nothing out of business is irresponsible, or at least not very nice, and that is what you're doing if you underprice your cakes, folks.
My cake was not a sloppy mess. I mentioned its faults in my constructive and positive advice. I also stated it was for a very good friend. It was essentially a GIFT at $175, was my point, and that the OP needed to charge more. Furthermore, judging by the number of people who post on this site requesting pricing help I highly doubt most people are "setting out to put real bakeries...out of business". YOURS is the only response that was "not very nice".
