Percy - Well technically you should be a member to get the books - but alot of WW Centers have a place where you can buy WW materials. They don't have the book you get when you join on sale - but they do have food companions, etc. They have points for TONS of stuff there.
I dont see why you couldn't walk in off the street and purchase one of those. Its very helpful (they are $8 in my area).
Don't tell them you aren't a member - just ask to buy one. Its worth a shot.
Good luck!
