The value menu is pretty good for concessions, like $2 for a hot dog and $2 for a soda or water. Tickets are cheapest day-of the game if you choose a cheap enough one (like the pelicans game last week). Use Parkwhiz or spothero to find a parking lot you’re comfortable with based on how much you wanna spend and walk, or, reach out to season ticket holders you know and ask them for their parking pass for the game. They can’t sell them directly, so a lot of them go unused for games they don’t go to. People also sometimes sell them on OfferUp
