Works for electronics too—not just groceries! Confirmed on my own purchase of an iPad 11th Gen A16 from Costco via Instacart for $207 after taxes (after cash-backs)

The deal shows "first time offer". Does this mean first time using PayPal (on Instacart), or first time using Instacart?

I have used instacart several times before. I think I have paid with PayPal for the first time!

I've never seen PayPal offers appear in the store checkout page. It appears in PayPal after the transaction completes.

To clarify, the 30% off Instacart is through PayPal and not exclusive to Costco.

Costco will cancel your purchase. Costco kept on canceling My same day Costco orders for electronics

Yesterday I went through instacart's website instead of going directly with Costco's website and it worked for me.

If you pay using PayPal wouldn't your discover charge be for PayPal and not instacart?

I have the 30% off Instacart on my PayPal which I added but where would the 40% off Costco Instacart come from? Instacart?

Can't find instacart gift card in Costco anymore, it will be great to stack it for more expensive items

I just tried to replicate this with the same iPad and Instacart flagged the transaction as suspicious, cancelled it, and now my account is under review. Hopefully I can reorder it, assuming my account is unlocked promptly?

Maybe iPad is getting flagged. I successfully ordered a mesh router with the $100 offer.
