Return address labels are one of my two top sellers. They are already a low-profit item and when on sale for as much as 50% off, it's peanuts. (I'm OK with that though 'cause I think all those peanuts help my store's overall "health".) If they could order just one sheet though, that would be an 80% reduction in peanuts. 😞 So I like that there's a minimum of 5 sheets. I think people use them to label more than just mail, they're useful for labeling personal belongings like books and CDs and video games, etc that might be loaned out. So 150 isn't really a whole lot when you can use them for multiple purposes especially since most people don't move very often so they have a pretty long "shelf life". (Which reminds me, they're also useful for when you are moving to label your packing boxes with your new going-to address.)
For ones designed specifically for wedding suites ... depending on royalty, were talking maybe $20 list-price for a set of five sheets. With 15-50% off that's $10-$17 per order. Even though that may be 3x's as many as they need, that cost is a miniscule drop in the bucket as far as wedding costs go. If someone really likes the design and especially if it matches whatever else they are ordering, I can't see the 5-sheet minimum being a deterrent since the cost is so minor.
