If you want to buy Whole Foods gift cards (which is why I got it) it flags it for fraud and doesnt let you. I was told you can spend at Whole Foods but not buy WF gift cards, even though it is a Prime Credit Card. Also if you buy WF gift cards online, you dont get the rewards since its from a gift card company and not Whole Foods.

Light Weight & Durability

The Universal 65W USB-C Laptop Charger works great and charges fast. I used it with my Chromebook and another USB-C laptop with no problems. The cord is a good length, and the charger feels sturdy and reliable. I like that it works with many brands like HP, Lenovo, Dell, Acer, Asus, Samsung, and Google devices. Great replacement charger for home, office, or travel use.
