Product review (5 stars): Better priced when you buy in bulk.
We were surprised when our fridge and freezer messaged us to replace their filters.  We didn't know that they even had filters.  But, we were pleasantly surprised that we could order the filters on Amazon and get a much better price for ordering in bulk (we ordered 6 filters in total).  Pros: Very well packaged filters that are very easy to instal.  Better pricing per filter when you order in bulk.  Cons: None noticed yet.  But our original filters lasted only about 5 months and we hope the replacement ones will last a bit longer.
