We both save money towards our phone plan by switching to Deadpool's Phone Company. I've been with them 2 years and never had a problem and saved lots of money. Plus I got a hilarious temporary tattoo in the mail once with Ryan Reynolds face. Pretty hilarious.
When they spend or send at least $5 (within 30 days of signup), you both can earn 1,000 points (redeemable for $10 cash back). Have them sign up and link their bank account or card.
Just fyi, 99% of rewards are worth $5. 1-in-100 customers can get at least $10; 1-in-1,000 can get $200. You can get up to $1,500 per year for referring friends.
However, I waited a little while and my stock when up to $7 and then I sold it after a year, so theres that. Happy trading y'all!
