Very annoyed that I need to pay for photos up front without having seen the proofs. How am I supposed to decide what I want if I don't know if I like the final product? If it's not great then I would only buy a couple. If they are great then I can buy a big package. How am I supposed to decide if I need retouching if I haven't seen the photo first? Also we get the forms on Friday night and are told to have money in by Monday morning?? Is that reasonable to you? Without seeing a product? Seriously disappointed. I'll see if Walmart does photos still.
