i dont know if this will help anyone, and this may be totally wrong of me to do. But i use enfamil and i seem to get way more similac checks! So, i buy the similac. Then i can return it to a grocery store for the brand i want. Publix never has an issue with this. I just swapped about 5 cans of different types of formula and got the enfamil gentlease i needed. It was a little more expensive, maybe like a dollar so i paid the difference. Seems a lot easier than swapping and mailing, etc. Just a thought
Like i said, this may not seem right to you, but i figure it all comes out in the wash in the end.
