It's not too late to sign-up with Presearch Referral Program.

You earn 25 tokens per referral. You become eligible for your 25 bonus tokens, per referral, once each referral has earned 100 search reward tokens, and has been active 60 days after their initial sign up. Members will also be rewarded for the referrals that took place before the kickoff of the referral program.
