CVS stores has their store brand Natural Fiber Supplement (compare to Metamucil) on clearance for 75% off.
100% Natural Psyllium Husk Fiber.
Many stores only have this marked as 50% off or even 25% off, but scan at the price checker to verify it is actually 75% off. cvs appears to be reformulating their brand to be closer to the named brand metamucil which dissolves much smoother. the current/old cvs brand is a bit grittier (i like it though).
prices for the sugar free variety: 36.8 oz (180 doses) – $4.62 (Orange) Regular price $18.49 23.3 oz (114 doses) – $3.32 (Orange or Berry) Regular price $13.29
