LINK card to pay for the headphones which I found interesting since I thought it could only be used for food and essential items. The first time the cashier swiped the card it only paid for $2.64 of the total $12.64 purchase. She then told the cashier that she needed to manually enter her number and ring it up as cash which then paid for the entire purchase. I was shocked to see this and even mentioned to the cashier that I sure could use one of those cards to buy headphones with. She smiled meekly. It is frustrating to see this. I hope Target watches for this a bit more closely in the future."
