I called the Nutrition Warehouse Vitamin Factory Outlet and they said the 100 count bottle of 1.8 mg tabs of NADH for $18.50 was discontinued. However, they have a bottle of 60 1.8 mg tabs for $19.16 coming out in the new January catalog. This is still a savings over the 30 count box of 5 mg tabs for $48.00 plus approx. $3 tax which I am now buying at the health food store. I asked them to send me the catalog so will order and post the results. They said it might be ten days before I get the catalog. I really appreciate this contact. The rep indicated that they have different prices from time to time. I imagine it depends on what deals they get on different products; closeouts etc. It sounds like a good place to watch for bargains. Carol Phelps [log in to unmask]
