Walking into a supermarket with a large trolley can be very dangerous. You tend to fill up your trolley and pick out things impulsively to satiate your cravings. Always visit the supermarket with a grocery shopping list, and stick to it. This way, you’re sticking to your needs and budget instead of buying unnecessary (and usually high calorie) foods.
You can also do the bulk of your grocery shopping online, with a list, and only “add to cart” foods that are already on your grocery list. Typically, if you spend above a certain amount, you will also get free delivery. This can save you time and money of having to drive or taking a cab or Grab ride home due to the heavy haul.
Similarly, to save even more, you can go online to do some simple research to find the best deals. Supermarkets and department stores sometimes promote their clearance stocks. Look out for these sales to get you the most bang out of your buck.
You can also sign up for money saving apps that can alert you for the best deals in town.
