Query: Better Than Half Off Store Price

Ditto to everything in the first review. Local drug store (CVS, Rite Aid) prices are in the $12-14 range last I checked. Costco almost faked me out on price by having a different dosage and number of capsules than the usual amount and labelling it "Extra Strength." When I got home and did the calculations the numbers didn't add up as I had expected. Turned out not to be the bargain I had expected for Costco. So the box went right back. And now I know to just stick with buying these in quantity to keep shipping prices down. And in Southern California figure 10% for sales tax. So buy five to ten bottles at a time. Same as store brand there is a lot of empty space in each bottle. So if you want to save space you can put the contents of about three bottles in one.
