Amazon's one-hour Prime Now deliveries were already available to customers in the San Francisco area, but the company is going a step further for football season. The online retailer is teaming up with the San Francisco 49ers to deliver supplies to tailgaters at Levi's Stadium during this year's slate of NFL games. This will certainly come in handy when fans run out of game-day essentials and can't easily drive out of the lot to go on a grocery run.Ordering is pretty straightforward, you just have to enter the venue's zip code to access a list of available items. At checkout, enter the address for Levi's Stadium and be sure to include which parking lot you're in and the nearest parking flag number. Prime Now is only available in three parking lots -- Red Lot 1, Green Lot 1, and Blue Lot 1 -- but the 49ers say that's where most of the tailgaters set up. Amazon's quick delivery service is available in the Bay Area from 8 AM until midnight and two-hour delivery is free. If you need something in an hour, you'll have to pay an extra $8.
