N/A

The smell of these vitamins would make anyone sick. I don't know why you would take the Super B Complex out of the clubs and now you only can only get them online, and when you go to Sams club website to order online it's always out of stock.

B complex

I was looking to add a b complex vitamin to my daily regiment. Sam’s club is always a great place to look. Quality and value is always great. I liked the size of these vitamins, they were not too big.

Members mark 300 ct advanced b complex pills

The Member's Mark Advanced B Complex , 300 ct tablets are not too big of pills they are small enough. If you have a hard time swallowing pills these are not to bad. I like them because they are an immune booster so that’s important.

Crappy way to treat loyal customers

l ordered this item & 2 other items 2 (TWO) times. The other 2 items showed IN STOCK both times, but were cancelled. This item came in a big box all by itself. NO WAY to treat loyal customers!!! For plus members, you increase the cost of membership, then You increase the amt needed to buy to get free shipping, now cancel orders of items that are IN STOCK. Getting rid of registers and trying to go cashless!! I do not like playing games, and Sams must really be trying to loose customers!!!! Its working!!!

New “Advanced” formulas of Members Mark vitamins

The new “advanced” formulas of Members Mark supplements have ingredients that are supposed to support hormonal health - fine for average users - not fine for cancer patients taking hormone suppressants. I will have to return this product for that reason. The previous Super B Complex product did not have that issue and is no longer available. The new advanced multivitamins have the same issue. Very disappointed.
