Costco.com and Visa Checkout have a deal:
Spend $250 or more in one transaction using Visa Checkout and paying with a Visa card, and get $50 statement credit.
A lot of people are buying Costco cash cards (2x $125 or $200 + $50). Some people are buying the $200 iTunes gift card for $165, plus other stuff.
One per card and member. Can’t stack with Discover 5% warehouse club category Q1. Need to pay with a Visa card.
