I haven't got a free crate, it asks me to pay straight away?
I got 5 regular crates yesterday and two gamescom. I sold the gear out of the normal crates to pay for keys for the gamescom crates with a few quid left over. Might be worth doing.
I think once they unlock sales on the gear from the gamescom crates, prices will rocket for a few hours then crash. Chance to make some cash.
