I don't mean to offend anyone, but here is what I have learned this far in my life. There are some people who think because they are who they are, they are "entitled" to things at a reduced or free price. Some preachers and their wifes fall into that catagory. I have some in my family that are like that and I have others in the same position in my family that would NEVER do that. Some just think they are entitled to get things just because they are who they are. Don't feel like you have to do this for them. They would be offended if they were asked to preach for nothing or a very small fee. Hold to your guns!
