I’m in the sticks, 30 miles away from even a medium size town (not city) in Mississippi and Jackson is over 100 miles away.,br>
Finding a Kosher shop here isn’t likely.
Another suggestion is to go to your usual grocery store in the area and ask the meat department to look at their distributor order book to see if they have those items available to buy....(having a guaranteed customer should clinch the order - may need to buy the whole case and freeze most of it)
Restaurants are another option, they have different distributors and a different product mix, if you are friendly with any restaurant owners - that could be another avenue.
A Sale is a Sale :)
