John... your prices may be quite correct. As I get older, I sometimes forget things. Like the fact the I bought a bunch of them on sale for $6 each about ten years ago. Yes, you can always wire "downstream". However, when your house is already wired, it's easier to replace them individually. GFCI breakers are not required in any juridiction I know of... I just like them.

Here's a good one for ya! I am an Engineer. I have managed millions of dollars worth of constrction. As part of the services my company provided, I was in the building inspection business for seven years, including home inspections. When I moved into my present house, a 45 year old bungalow, I made a list of electrical upgrades and went to see an old buddy. He had just retired and his son had taken over the business. Sonny arrived a couple of days later and went to work, as did I, fully confident that I would get a top notch job. When complete, I looked over the work in the house and was pleased.

About six months later, I blew a fuse in the garage disconnect. When I opened the box, I nearly **** myself. Sonny had wired the new exterior GFCI to the line lugs in the box. The next time I saw his old man, I told him about it. He said, "Well, it's hard to find good help these days." Always was a joker. But, you just know what happened when he next talked to sonny. Sonny never did contact me to find out why I wasn't throwing any more business his way!!!
