Bizarrely, these offers don't show up with my Capital One-provided Priority Pass membership (with unlimited visits) but do show up with my PenFed-provided one (where I have to spend $32/visit.) If the code doesn't count as a lounge visit (which all indications suggest that it doesn't) I might have to try out the SJU offer. All the other offers I could find were simply 10% off of (likely overpriced) retail stores, so that's not terribly exciting.
