GET $5 OFF: Amazon is offering $5 off a Grubhub order of $15 or more when you link your Prime and Grubhub accounts.

Amazon Prime comes with a ton of perks: Free same-day delivery, streaming deals (including access to Amazon Music Unlimited), fuel savings, prescription savings, and so much more. If you’re not a member yet, you should definitely do a little math to see if the benefits could work for you.

Did you know that Amazon Prime members also get free access to Grubhub+ for the duration of their account? So, if you have a Prime account, you also have a Grubhub+ account, which gets you $0 delivery fees, lower service fees, and exclusive savings. According to Amazon, this little perk can save you around $336 per year.

And if you haven’t linked your accounts yet, now’s the time to do it. Through June 30, Amazon is offering $5 off a Grubhub order of $15 or more when you link your Prime and Grubhub accounts. You just need to use the promo code FIRSTORDER at checkout.

It’s a solid excuse to order lunch, but the real value is the ongoing perk. Once linked, you keep that Grubhub+ membership for free as long as you have Prime — and don’t worry, the fine print says it won’t automatically convert into a paid plan later. That membership unlocks $0 delivery fees on eligible orders over $12, lower service fees, and 5% credit back on pickup orders (just keep in mind those credits expire after 90 days).
