i'm not sure if you can get it at WalMart like all the other Similacs but I know for sure that you can order it off the internet at the similiac website. they have all the different similac formulas that i have never seen out in the stores. and you get better deals and offers too because i think the neosure formula is little more expensive than the others.
We used it for a long time. You can get it anywhere. Target, Walmart have the best prices. Babies R US, and the grocery store, CVS, Walgreens all have them too. But they are more expensive. Also MAKE SURE you go to strongmoms.com and register they will send you a FREE CASE of it, as well as $25 in valchers!!!
