Example Input: Box arrived in horrible condition. The contents inside appeared to be unused (still wrapped and sealed), but the box looked like it had been opened and closed several times, even kicked around a bit. This is a gift, so I had to repackage it in a nicer box before wrapping.
Example Output: 3

Example Input: Convenient to be able to have multiple replacements on hand at a much more reasonable price. Water seems to taste as good when compared to the LG brand filters I used previously.
Example Output: 4

Example Input: I ordered two packs of these as a gag gift for a friend. A month later a third package somehow showed up at my parent's house stowed away in one of their other orders. Well played, Amazon.
Example Output:
3
