Nancy-
I found that Toys "R" Us and Babies "R" Us had the best prices on similac formulas. Go to Similac.com and sign up for all kinds of coupons from Similac. Anywhere from $3 to $5 off cans of formula. I do not believe that you can buy the Similac Sensitive at Sam's Club. I used Similac Advanced for my daughter and they carried that one. Along with Member's Mark (store brand). Hope this helps you out.
