I email Trader Joes about this sauce and they responded the next day with this-
Thank you for taking the time to contact us. The Mexican Red Sauce was
discontinued due to slow sales. I will let our buyer know that this is
missed. If we receive enough requests to return a discontinued item,
our buyers will sometimes give it a second run.
Trader Joe's approach to the grocery industry has always been quite
different from the mega-chains. Because our stores have such limited
shelf space, if our customers aren't buying a product, we take that as a
majority vote against it and we will bring in something else in its
place.
Again, we appreciate your feedback and it will be shared in the next
marketing meeting.
Sincerely,
Ana
