aperry - that's how many your local OM delivery center has in stock. It varies from city to city.
BTW, most stores in my area received about 200 boxes of these things so I don't think they'll sell out very fast.
Also, to correct what someone else said in the other thread, (not that it matters) but the 200 CDs come in 2 100-spindles. (No nifty plastic cases like the regular 25, 50, and 100 spindles - just a big plastic rod down the hole in the center)
