We've been looking at our finances this month so we can pay down some debt that's been hanging around and look toward having a reasonable household budget.
One thing I'm not sure about is how much to allow for buying books. I mostly get by with free ebooks these days, and print copies borrowed from the library. Every now and then there's either a discounted ebook I want, or a deal in the local bookstore that's hard to pass up. Yet I sometimes feel guilty about spending money that way because of the existence of libraries and my already-large collection of ebooks.
Does anyone else feel the same? Do you budget for book-buying at all or just wait for deals?
