They are often marked up well over 10,000% if you can find them (i.e. on an auction site). I've seen 5-packs of masks that typically cost $15-$20 sell for $1500 (no exaggeration). You can also take a chance and buy Chinese masks but you run the risk of getting something totally fake or just defective.
As far as hand sanitizer, various stores get it in stock periodically but you can still find isopropyl alcohol fairly easily. My local Wal-Mart gets more of it in every few days (sells out the same day though). Just get some rubbing alcohol.
