Purchasing a new refrigerator today. I have the chase ink. The plan is to go to Officemax online and purchase gift cards then go back into ultimate rewards and order through Lowe's website. Many times I have read that this will count as 5x even though I am buying a gift card. When I went through the portal there was a disclaimer that stated you can not get it for gift cards. Do I need to go to the store or does it work anyway? Patiently waiting and thank you!
