Apple today sent out emails for a new Apple Pay promotion, offering a $5 discount on groceries when you spend $35 or more through Instacart. To get the discount, you'll need to use Apple Pay and shop in the Instacart app.
The discount will be applied automatically during the checkout process and will be available until 11:59 p.m. Pacific Time on October 20, 2019. Apple says there may some restrictions on geographic availability and the offer can not be applied to alcohol products.
Apple's promotion also provides links to other grocery delivery apps including ACME, Cub, Publix, Safeway, Shaw's, and Star Market.
