We have finally figured out the best way to purchase groceries. The big grocery stores have questionable quality, besides we like to support local poeple. The morning market has good quality, but who wants to get up at 7am to go to the market to shop for dinner? The evening markets are convenient, but quality can be bad (who wants to buy squid that's been sitting out in the sun all day?)
This couple drives by our house at around 11am every day. The quality is unsurpassed and they have a surprising amount of variety for such a small venue. The cooler is packed with meats and seafood, veggies, and dry goods like salt, sugar and coconut milk.
Their journey starts at about 12am buying groceries to stock the truck. This is why their quality is the best. They get the most fresh meats and seafood before the other markets do. Her husband drives their truck while she sits in the back all day long. If she doesn't have what you want you can request it to be delivered the following day.
They have been doing this for about 12 years. Their days are long but they seem very happy, although one day I found her sleeping as they drove up.
