Tienda Casa Paloma in Overland Park used to have some really incredible Vera Cruz style tamales (wrapped in banana leaves, not corn husks) that you could buy in bulk. It's changed owners, and is now called Gavinos, but I think it's owned by the folks that used to cook there.
This thread reminded me I have neglected trying their tamales since the ownership change. Will try, ask about pre-made bulk tamale purchases, and report back.
