Product review (5 stars): Great seller
As other buyers mentioned, I got a personalized email message from this seller in follow up to my purchase of this product. Since customer service is extremely important to me, I thought that was a great touch! The 3-pack of water filter cartridges were advertised to me on Amazon as being Supco brand.  However, that is not the brand I received. My 3-pack is Eco-Aqua brand. This really doesn't concern me, since the Eco-Aqua cartridges work in my Maytag water filtration unit. I paid $15.50 PER cartridge ($47.00 for the 3-pack)  and I thought that was extremely fair. I was told I might pay as much as $45 PER cartridge for this Maytag accessory. I am very happy with both this product and it's seller -- DeepDiscounts.
