pequeñas tiendas in Playa Blanca or Barra de Potosí

Hola !!
Coming back to Zihua for a month and spending first part of vacation on Playa Blanca. Will there be small stores to pick up beer, wine, ice, snacks, bit of fruit, bread cheese maybe.... etc on the road in? Where abouts please? I won’t be cooking

The enramada Marlin has a store front on the airport road halfway between the airport and La Barra de Potosi. They have beer, wine booze, water, ice and most other bare necessities. The enramada also has a pool and a decent grub.
