Sarcastic doesn't fit filter canisters that are too wide Trying to get a refund is very difficult unless you can find a UPS store that does it Don't give them if you happen to print a barcode-only label, no place other than a UPS store will accept the barcode, so I'll stick with it. And it's awful, I'd recommend just going to the store and buying them to make sure you see what you get, other than the hassle.
