Visa was the second most preferred gift card, followed by Walmart and then Target. If you are able to find a good deal you should take into account the 45 day guarantee and get spending! We particularly liked the Cardpool app, which gives you access to a digital wallet and allows you to buy gift cards on the go; maybe even while waiting in line at checkout. It offers a day balance guarantee from the date of purchase, which means you’ll be able to use the full value of any gift card you buy within days.
