If the dad in your life is a gamer, Swagbucks (the online rewards site that puts cash back in your wallet) has an AMAZING offer through Gamefly where you get 2500 SB (which is the equivalent of $25 in gift cards) for signing up.
Gamefly allows you to rent games for lots of different consoles including Xbox 360, Xbox One, Wii, PS3, PS4, etc, with no late fees ever. Members can also play 100’s of PC games for free! You can try it out for 2 months at a price of $10 AND get 2500 SB by using this link!
Haven't tried Swagbucks yet? This is a great way to do it, and when you sign up through the link above and get your 2500 SB, you'll get a bonus 300 SB at the beginning of July.
