I'm sure this has been posted before, but I couldn't find it. Customer wants a simple flower bed done. Found all of the prices at Lowes + Home Depot herself. She wants to just buy them herself and then give me the receipt to go pick them up. I mark up materials even when I buy them at retail stores in order to cover travel time, taxes, etc... When my business has grown in size I certainly will not be doing this type of thing, and I don't want to start with her. How do you all go about this type of thing?
