If you rent a game from blockbuster then return it the same day, can you rent a different game for free?

No, if you're a new customer and complain or raise hell about it they'll let you get away w/ it the first time, then block you're account from doing it ever again. You can pay for a Game Pass and then switch it out as many times as you want. Its a program where you pay $20 a month and can rent one movie/game out at a time and swap it for something else as many times as you want and never pay extra or keep it as long as you want and no late fees.
