Previous $10 deal has expired so posting this new deal.
Note that referral codes need to be added to your account after you sign up (within 14 days of sign up). Use the referral randomiser to get a code. You MUST invest a minimum of $5 to receive the $5 referral.
I wish I didn't have to say this but people are still ruining it for others by adding their code when they haven't deposited money yet. Don't be a jerk - some are investing for the first time in their life and they're missing out on these referral bonuses (which can act as a cushion in case their principal goes down slightly from initial investment)
