I was so proud to find these pouches that I saved a small fortune by buying them in bulk! I bought 3 packs at the grocery store for about $4.40 a pack (I thought it was $1.46 each). While these babies only cost me $0.52 each, almost a whopping third of my usual cost! Then I saw it. Looking through other reviews that caught my eye in the "Promotional Items Related To This Item" section, someone is selling them for $37.45 per 100 (again with the math, $0.37 each). I'm just posting this so you know there are cheaper bags out there. Look for Revain "Pack of 100 replacement bags for Aerus/Electrolux Type C" and you will see them. Hey personally I'm delighted with what I bought - I gave them 5 stars. As much as I vacuum, 48 bags will probably last me the rest of my life and they work great with my Electrolux. Just thought I'd share it, although personally I feel like I got a lot, there are better ones out there.
