What can you get for $5 on Amazon? How about a set of unicorn-themed temporary tattoos, or a Cydni Lauper compilation CD, or a potholder that looks like a Russian nesting doll? Any of these fine treasures can be yours for free, if you can convince one of your friends to buy something using the Amazon Shopping app for Android. Oh, and they'll get $5 too, just for being invited. Russian nesting doll potholders for everyone!

The latest update to the shopping app, version 5.9, says as much in the changelog.

Invite your friends to use the Amazon Shopping App. We will give your friends a $5 coupon to shop at Amazon. We will also give you a $5 coupon, when your friends make their first purchase in the app (currently in US only).

Here's how it works: open the Amazon Shopping app and log into your account. Open the side menu and scroll down to the "Personalized content" sub-section, then tap "Invite Friends." You can then invite people from your standard contact list, or just send them a code. They'll get $5 to use in their Amazon account, and if they download the Amazon app, then use it to make a purchase (as long as they haven't bought anything from the app in the last 12 months, per the terms and conditions of the promotion), you'll get $5 too. As noted above, the promotion is only good for users of the US version of the Amazon store. Sorry, international readers, it's not our fault.

Do you want $5 of Amazon credit, but you don't have any friends? Use Artem's code (above) and download the app. Here's the text for the refferal link: https://amazon.com/mpr?referralcode=ARTEM2179N&ref_=mpr_tr_ss. We promise he'll use any credit he gets for the good of the site, probably in the form of hard alcohol.

The download should be disseminating through the Play Store now, but if you can't get it for whatever reason, the latest version of the app has been uploaded to APK Mirror.

Last updated: September 4, 2015

These Amazon App Referral Program (the “Program”) Terms and Conditions are in addition to the Amazon Conditions of Use, to which you agree by using the Amazon App or Amazon Shopping App for iOS, Android, or Fire OS (the “Amazon App”). To the extent the Amazon Conditions of Use are inconsistent with these terms, these terms will control with respect to the Program only. We will make all determinations under the Program in our sole discretion.

For you to receive a promotional credit of $5 off a purchase of $10 or more for inviting a friend to try the Amazon App:

You must have a valid Amazon.com customer account;
The customer you refer must use your link, sign in to the latest version of the Amazon App for iOS, Android, or Fire OS, and verify their phone number;
The referred customer must not have completed a purchase from the Amazon App within the preceding 12 months and the phone number associated with the account must not have received a purchase discount during the lifetime of the Program; and
The referred customer must place an order using the Amazon App for physical goods (excluding gift cards) shipped by Amazon and must not cancel that order prior to shipment

Each purchase discount can be redeemed only on items sold by Amazon on Amazon.com, is valid for one-time use only, and is non-refundable - if you use a purchase discount to purchase a returnable item and you return that item, the amount of the purchase discount used by you to pay for the item will be deducted from the total amount of the refund.

You may not use purchase discounts to buy gift cards or to pay for shipping, handling, taxes, or any other applicable transaction costs. We may also specify certain products that are ineligible for payment using purchase discounts from time to time.

Purchase discounts are issued to a single Amazon account at our discretion and cannot be transferred, bartered, or sold.

Participation in the Program may require you to submit personal information about you and the customers you refer, such as name and email address. You agree to receive communications from us with regard to your participation in the Program, and to allow us to communicate with referred customers about your participation (for example, by disclosing to them that an invitation was sent by you). Any information collected from you or your referred customers as part of the Program will be subject to Amazon's Privacy Notice.

If you participate in an Amazon affiliate marketing program, including Amazon Associates, you will not receive a purchase discount on any transaction for which you receive affiliate advertising fees.

We may void your purchase discounts, terminate your eligibility to earn purchase discounts, or terminate your account, or the accounts of customers you refer, if you or they take any of the following actions:

Open multiple accounts, including with different email addresses or phone numbers, for the same person in order to generate additional purchase discounts;
Refer customers using spam, display advertising, sponsored links, unsolicited emails, or links on message boards or forums;
Use false names, impersonate other people, or otherwise provide false or misleading information to us;
Offer any incentive to others to register new accounts;
Violate these terms or any other of Amazon's terms and conditions in any way; or
Participate in the Program if doing so would be prohibited by any applicable laws or regulations.
We reserve the right in our sole discretion at any time and without prior notice to you to add to, remove, or otherwise change these terms, including, without limitation, by changing the amount of the purchase discount, modifying how you may earn and spend purchase discounts, modifying the duration and expiration of purchase discounts, requiring or modifying minimum purchase amounts for use of purchase discounts, changing the maximum amount of purchase discounts that you may earn, and discontinuing the Program entirely. We will post an updated version of these terms in the Amazon App, and you will be deemed to have accepted such changes by continuing to use the Amazon App or to participate in the Program after the date such changes are posted.
