Keeping leafy greens fresh is quite tricky. It is always advised to use them as soon as purchased. But if you are planning to use them later in the week, you can store them by first removing its stems, rinsing, and drying them thoroughly. When dried completely, store them in a paper bag or cloth bag. Make sure that they are packed loosely, as squishing greens together will make them wilt faster. Also, stay away from plastics as storing them in it will just trap the moisture that will make them rot.

In a humid and tropical country like ours, it is quite tricky to store onions, garlic, and potatoes. They must be kept in a cool dry place. You might think that storing them in the fridge is ideal, but it really isn't. Storing these in the fridge will just make them soggy and moist. It is best to store them in a drawer or pantry cabinet where there is air circulation. Placing onions, garlic, and potatoes in netlon bags or perforated paper bags also helps. For potatoes, make sure to cover them with cloth to avoid light exposure. Also make sure to store onions and potatoes away from each other. If stored together, potatoes tend to speed up rotting of onions. 

Once an onion is halved, tightly wrap it with plastic or an airtight container and store it in the fridge for up to two weeks.

After purchasing, make sure to remove them from the original packaging and transfer them to a plastic wrap or an airtight resealable bag. Make sure to tightly wrap them and let out as much air as possible. Also, keep in mind to portion them by how much you would be needing in a single meal so when you remove and thaw items from the freezer, you wouldn't need to refreeze them again. If frozen properly, cuts of pork, beef, and chicken can last for months.

For processed meat like ham, hotdogs, patties, and bacon, these can be kept frozen for up to two months.

When buying fruits such as kiwi, melons, bananas, papayas, mangoes, and avocados, it is advisable to buy half of the portion ripe and half unripe. Place the ripe fruits in the fridge (in the crisper drawer) and that will make them last for up to a week. Meanwhile, store the unripe ones in a paper bag and let them sit on the kitchen counter for days. This way, these fruits will continue to ripen and you wouldn't have to go to the market every week.

For fruits such as grapes, blueberries, cherries, and strawberries, keep them in plastic bags with perforation to keep them from getting soggy. 

Meanwhile, you can stock up on apples as these last quite long when refrigerated, for about 3-4 weeks.
