Buy the generic version. We get a really big one from HEB for $20 (about 3 times the size as the similac can). Major grocery stores/pharmacies usually have their own brands.
costco fomula, it has all of the same ingredients as similac and it's double the size for $20. it's milk based and my daughter had no issues with it. it saved us SO much money since we do not qualify for wic. her pediatrician actually recommended it
I buy Walmart brand. If you read it, it says comparable to Similac. Has all of the different choices just like Similac, but half the price. Only $20 for the big container. That's all we've used since the beginning 😊
