Product review (5 stars): Strange Pricing
It shipped fairly quickly.  It went in easily.  Product is great.

I was surprised that if you buy them in bulk you PAY MORE.  I paid $34.02.  If I would have gotten a two pack, they'd cost $38.75 each; same if I bought three.  It was $38 had I bought a four pack and 37.50 if I bought six.

It's over $20 cheaper to buy six individual filters rather than the six pack.

Anyway, it's a good product.  You should buy one...but only one.

P.S. I shipped them supper slow and paid no freight, so that didn't factor into the cost.
