Hela's House of Dark Delights for Tunnels & Trolls

"We have two kinds of magical armor," your hostess states, "but they are very expensive. One type costs 100 times its normal value, and the other type costs 1000 times its normal value. If you cannot afford either of these types, I can give you a steel cap that takes three hits instead of one. I cannot tell you what the armor does, until you tell me which you intend to buy." If you take the steel cap, you have it, and are led out.
