You make a large purchase. You assume everything is correct. Months later, you notice a charge you don't recognize. Now you're trying to remember what happened. Was it a fee? A separate purchase? A duplicate charge? 😵💫 💚 LILY TIP: For larger purchases, keep the receipt, agreement, and confirmation email until you're sure the transaction is completely settled. It's much easier to investigate a charge when you have the original paperwork.
