They're already teasing about the next pack (The gurus are hinting heavily today)

I made my own retail location that is a grocery store for that very reason, @SheriSim57. No more limit on how much of an ingredient I can buy. Most of the ingredients can go into the LICE Retail Freezers which makes for unlimited supply when played sims shop there even if you only originally put 1 in the freezer for sale. It also means my sims can buy perfect quality ingredients because that's what the Sim who stocked the store grew.
The only downside...it's a lot more expensive. :lol:

The only ingredients in the entire game that you cannot sell at a retail location are the wrapped red and white meat. Fortunately those are already available in unlimited supply from Lobo's grocery stand.
