Sure, I could use a plain envelope for my budgeting and receipts, but they tend to get overlooked and misplaced because they just don't stand out. I've also tried using plastic envelopes, which I like, but they're bulky. There's something really nice about being able to tuck the entire envelope into my monthly files when I close out my budget each month. All the expenses are right there on the envelope, making it so easy! It doesn't hurt that they're pretty and it's so easy to print out more whenever I need them. Great price & simple solution.
