Got one
9GVG4-Q0B7N-RFDWQ

GOT ANOTHER
9MHEM-MIW0W-4B6Q2

I forgot to mention that it took me a couple refreshes to get through, probably due to heavy traffic, so there's that

GOT THREE
9NQX6-D2IYP-3AC7M

fetch those captchas were hard!

they were nice enough to give me a code that was already used

luckily i got a second one that worked

I dunno how big their giveaway is but I've heard that the keys are drawn from a giant list so it's quite possible you might run into duplicates; I got a working key on the first try but just like you my friend had to get a second one to get his since the first one he got was already used

Cool, got one on my first try
