Prime members can get up to 50% off a GrubHub order during October Prime Day — here’s how

Lucky for Prime members, discounts during Prime Big Deal Days don’t stop at those front and center on Amazon’s homepage. You can also access a slew of other exclusive promotions, but they’re not as easy to find. As a shopping editor who’s been covering Prime Day for five years, I know the ins and outs of the mega sale and what a Prime membership gets you. Below, I broke down all the “secret” Prime Day deals you likely don’t know about, including those available through Buy with Prime, GrubHub and travel sites like Avis and Carnival. I’ll frequently update this list throughout Prime Big Deal Days, which is from Oct. 8 to 9.

Beyond the discounted products on Amazon’s website, Prime members can use the Buy with Prime feature directly through participating brands’ websites. Here’s how to take advantage of these exclusive deals:

1. Browse Buy with Prime deals here. When you find one you want to purchase, click on it to visit the product page on the brand’s site.
2. On the product page, scroll down to the blue button that says “Buy with Prime.” You’ll either be prompted to sign into your Amazon Prime account or get automatically logged in.
3. Select a payment method and address saved in your Prime account, then complete the checkout process.
4.  Since you’re buying through Amazon Prime, you’ll get free, fast shipping on your order. You can track it through Amazon’s app or website.
