Pacquiao (57-5-2, 38 KOs) is looking to defend his WBO title, while Mayweather (47-0, 26 KOs) will put his WBC and WBA crowns on the line.
Tickets for the bout were costly and limited in supply. But even for those who didn't shell out for tickets, the fight will carry a hefty price tag.
The main pay-per-view undercard begins at 9 p.m. ET. The Mayweather-Pacquiao bout is expected to begin at approximately 11:30 p.m. ET and is being offered by DirecTV, Verizon Fios and Time Warner Cable, among other cable services. It's expected to set PPV records, but you'll need to spend $90 to watch in standard definition or $100 to watch in high definition.
SI.com rounded up a few ways that you can save money on the fight. There's no easy (and legal) way to watch the fight for free, but the ideas and promotions below give you a few options.
Switch to DISH
If you're looking to watch the fight for free, there aren't many options. One way is to switch to DISH and agree to a 24-month contract with the company. If you do that and use the code BOXING, you'll be able to watch the PPV of the fight at no charge. The DISH deal expires the day before the fight.
In terms of watching the fight at a discounted price, there's more flexibility. Tecate is offering a $50 rebate towards the PPV by purchasing three 18-packs. There's also options for a $15 or $30 rebate.
Leave the house
Another way to save money is to watch the fight at a bar or restaurant showing it and pay a cover charge that will almost certainly be less than what you'd pay for the PPV. Or you can pool together with friends to purchase the PPV and watch as a group at someone's residence.
If all else fails, it might just be the perfect time to take a vacation to Mexico, as the fight will air for free there.
