• You can get a free year of Grubhub+ with an Amazon Prime membership. 
• During the Prime Early Access Sale on Oct 11-12, you'll also get 20% off a Grubhub order. 
• Grubhub+ usually costs $9.99 a month and gets you free delivery on food orders, plus occasional freebies.

During Amazon's second Prime Day on October 11 and 12, Prime members in the US can receive 20% off (up to $10) on a Grubhub order using the code Prime20.

The 48-hour deal is part of Amazon's October Prime Day (also known as the Prime Early Access Sale), which starts tomorrow and runs through midnight PST on October 12.

The deal comes as part of Amazon's deepening partnership with Grubhub. During Amazon's first Prime event in May, the retailer announced it was adding a year of Grubhub+ for new and existing members as one of the benefits if being a Prime member. With Amazon's offer, a year of Grubhub+ is now included with a $14.99 per month Prime membership fee — a savings of nearly $120. 

Grubhub is a food delivery app that allows you to order food from local and chain restaurants in your area. While the app is free, you typically pay a delivery fee on each order, ranging from $2.50 to $7.50. Grubhub+ lets you to avoid the delivery fees on your orders for $9.99 per month.

How to claim 20% off your Grubhub order during Prime Day

On the day of the event simply enter the code PRIME20 at checkout to save 20% on your order. The offer can only be used once, on any order over $15, and taps out at a maximum discount of $10. 

To claim the 20% offer, you'll need to be signed up as a member of Grubhub+ via Amazon Prime. We've outlined below how you can join for free as a Prime member.

How to claim a year of Grubhub+ with Prime

New and existing members can visit Amazon's Grubhub+ page and click the "Activate free Grubhub+" button. You'll be prompted to set up or sign into your Prime account and then rerouted to Grubhub. 

Who is eligible?

All Prime members are eligible, including Prime Student members. If you are already a Grubhub+ member, you can still claim the offer. The only exceptions are Grubhub Campus, Corporate, and certain existing partnership members. 

What are the benefits of Grubhub+?

Grubhub+ lets you order food from the app with unlimited $0 delivery fees on orders over $12 at eligible restaurants. You can also get free food and occasional member discounts, like $10 off a pickup order every month. We've found that if you order food at least once a week, Grubhub+ is worth it.

What are the other benefits of Amazon Prime?

Aside from a year of Grubhub+, an Amazon Prime membership comes with a number of useful benefits. Chief among them are free shipping on most orders and access to the retailer's huge sales event, Prime Day and its newer Early Access holiday event in October. If you're unsure of whether Prime is for you, Amazon offers a free 30 day trial that allows you to take advantage of the benefits before committing.
