I've bought a few of these from this seller. I think it's a pretty good price (at least in Australia) and the seller is prompt/reliable and seems to have an unlimited supply. AUS $25 = approx US$18.18 (excluding postage, as of 11/12/15) OAKLEY RX METAL TORPEDO VAULT SMALL PROTECTIVE HARD CASE FOR READING GLASSES NEW P.S. I'm not affiliated with the seller in anyway at all, except that I've purchased a few of these cases from them. According to the rules for exchange, I'm in contravention of "In the Oakley Exchange areas, you can sell any authentic Oakley item that YOU own." Hope it's still ok to post this here.
