Currently, I take my COGs and multiply that by 4.25, which gives me my prices. I increase my prices every year at the end of summer right before I get into my busiest season. I don't give a heads up on when I change my rates, it's just something I do. I've never had a complaint. When a repeat client contacts me for a session after a rate increase, I just let them know there have been a few changes since their last session and send them my rate catalog.

I have starting prices on my website and if requested, I will send a PDF of my rates, but that doesn't happen often. Once someone books with me, I send them my PDF of rates so that they have it, but I find most don't read it, which I'm fine with. At their session, I give each client a rate card along with other materials, but I don't have everything on my rate card -  just the things that I want them to buy. I do all my ordering online, so they don't receive rates again until they order. 

I offer three print collections that are geared around albums and then I offer two digital collections. I only offer two different albums now as I felt that I was giving too many options and clients were having problems making a decision. Much better now. I only offer things that I would want myself, fit my mission statement/business plan and work well with my style of photography. I'm very selective in what I sell.
