Gift card deals: Uber, Instacart, Grubhub, and DoorDash
Source: Android Authority

All of these offers come in limited quantities, so you might want to hurry before they run out! You can check how many units have been claimed on the Amazon page, right above the “Add to cart” button.
If you’re already a frequent user of any of these services, you might as well get yourself a gift card. It’s basically free money and makes a great gift for friends and family. Many of us use these services for food and grocery deliveries, among other products.
The best offer comes from DoorDash, which essentially gives you a 20 % discount. The others are 15 % offers—still great, but it’s nice to get more. It all depends on what you already use.
Keep in mind that some of these offers are for eGift cards, while others are for physical cards. The only difference is that you’ll have to wait for physical cards, whereas eGift cards arrive in your email within minutes.
Make sure to jump on these gift‑card deals as soon as possible. Quantities are limited. For example, 73 % of the Instacart gift cards have already been claimed, so those are nearly gone.
