Review on Enhance Aquarium Filtration with Marina Slim Filter Carbon Plus Ceramic Cartridge - 18-Pack by Barbara Lawler

Bought for a neighbor thinking it came with 18 cartridges as 18 packs are listed and in the picture It says 3x per pack so choose a size 6 made me think that 6 counts = 6 packs and 6 x 3 = 18. My neighbor only wanted to spend $3 for 2 cartridges but I convinced him that $10.19 were a good deal for 1 cartridge. This is a misleading post. The only thing that solves the problem is the description, which says 6 cartridges in total (2 packs of 3 cartridges per pack). now i have to give my neighbor back his money and take the hit and all i tried was to help him.
