"$20 for $50 of Groceries
Hey all, if you use the code 30PAYPAL and checkout with PayPal, you can get $30 off your order of $50 or more on Instacart!
ETA: Thanks to the folks in the comments, it expires 1/1 at 2am EST, so basically, expires 12/31 :). I've also seen elsewhere that it is limited to around 84,000 codes uses. I'm so glad this has been useful!"
