I checked Kroger's website, which had some strange problems. You can't sort by lowest price and there are approximately 2.5k results for "milk". The "dietary preferences" filter does not include "lactose intolerant" or anything equivalent for milk alternatives, despite all milk alternatives being in the search results. The only one that looked genuinely useful (but not for me) was "Gluten free".
That being said, I did a price check and found that soy milk was not cheaper than regular milk. Kroger milk is $3.29 for 1gal and soymilk is $2.59 for 0.5gal.
