Yep, been there done that! Sometimes we just go ahead and get what we need without thinking about the cost. If I've been away from the LQS for a few months it seems like sticker shock sets in rather quickly. I am fortunate enough to have a rather large stash and seldom have to buy everything. That really helps on the total cost of making a project. I've always bought a little extra for just in case and have been happy to either use it or add it to my stash. This hobby of ours is what it is, it can be highly costly or it can be rather frugal. We usually have a choice.
