I wonder if Valve will do something for April Fool's this year. Maybe they'll release a legitimate update that people will think is a joke because of the date but will actually be real, that'd be fun to see.
I think they sell them cheapest on source op but I could be wrong.
In a stroke of sheer lack of self-control, I bought seven from the Market a little bit ago. I don't really like dealing with Paypal and middlemen and rep and all that mess even if it does save me a few bucks in the end. I saved enough money by buying from the Market instead of the Mann Co Store that I basically got a free Key anyway so I'm not terribly upset about it. I still should not have access to my bank account at 6:30 in the morning.
so why are salvaged crates so important?
iirc they just contain the most basic of weapons (ambassador, direct hit)
You know all those weapons are Strange, right? Salvaged Crates drop much less frequently than normal Crates and generally contain the most wanted Stranges.
