hmmm...the cheapest I know of in terms of retail is Mike's (1fast400.com)...which is 19.95 for 100 100 mg. caplets, which is 10 grams, so 1.995 per gram....if you bought a hundred grams worth (10 bottles), it would be 199.50....and Mike has discounts on over 5 bottles, so it would actually run you $18 x 10 = $180...
So 100 grams for $240 is overpriced
