You might be able to get the same thing cheaper at the drugstore.Usually sites like this end up being expensive. Let me check:90 tablets 384 mg Usually $21.95 on sale for $13.17 http://www.walgreens.com/store/product.jsp...&id=prod1033069 300 tablets 250 mgs each for $6.99 So I might try the pharmacy down the block first.K.
