Product review (5 stars): Samsung Refrigerator Water Filter
This filter was $30 from Amazon and it was eligible for Amazon Prime, therefore, no shipping charges.  I priced this at Lowe's and it was $44.  And, it's the same filter.  I considered buying a two or three pack, but it was not eligible for Prime shipping and was actually more expensive than buying single filters.  Hmmm, I think Amazon needs to change that...
