As the other posts were removed for referral spam, Finder is running a promotion where if you download their app and create a wallet, you'll receive $5.53 to $100 of free Bitcoin. The codes are as follows:
PARTY8800 - $5.53
PARTY6600 - $7.83
PARTY3300 - $8.07
PARTY2200 - $12.79
PARTY968 - $22.85
PARTY110 - $50.88
PARTY22 - $100
I suspect the $100 prizes have been claimed by now. You'll need to verify your identity to create a wallet, so it depends whether the highest available amount is worth your personal information. It wasn't for me.
Enjoy!
Edit: Just to clarify, the number after PARTY indicates the number of prizes they're giving away for that amount (as per the T&C).
Gosh how many $22.85 codes do you have?
