The disparity in pricing is why I think these posts about 'what should I charge' get confusing and why there is no one answer to this question!
I just recently started charging for my work now that we have a CFL here in Oklahoma and I can tell you that my prices are consistent...if not more...than most custom cake bakeries around here. One reason is because I think my skill level is equal to most of them (with the exception of fondant...I don't cover in fondant)...and another is because I have to pay retail for ingredients-- I don't use cheap ingredients. I can't justify wholesale purchasing at this point because I really don't want to become a full time bakery.
Have I lost a job or two because of my pricing? Yeah...and I'm glad. Who wants to work for nothing? I've done that and now that I have the experience, it's time to get back some of that sweat equity I put out there.
That being said, I do like to hear the various price points from everywhere...however I would never use someone else's pricing on CC or anywhere to make a decision on what I should be charging... nor would I ever purposely undercut someone else. If you lessen your pricing just to get a job, then you are also lessening your own value and talent in the eyes of your customers.
And that's my 2 cents worth! ;D
