The one I tried to visit had closed, so, since I was parked, I went into an antiques store. I saw four lovely Zane Grey books from the 1930's and was really pleased until I saw that they were $10 each. Blech. I left them on the shelf. A bit of research at ABE Books showed me that my first instinct was correct...they were priced waaaaayyyyyy too high. I was pleased, though, to pick up a battered 1905 copy of The Return of Sherlock Holmes for $2, which might be a buck more than it's worth but the shipping would make up the difference.
Happy now. Got my book-buying fix for the day. Hope it holds for a while.
