They found that only 3% of the people they asked were able to spot the best deal. If you follow the link you will be able to have a go yourself and see if you are successful. In order to get around this problem and make sure that you are getting the best deal, there are a number of things that you can do.
Compare prices online before you shop
Most retailers have websites these days which list the products they sell with the prices. This means that you can have a chance to see what you will be buying and decide on which to buy before you shop. This could take a while, but if you are buying expensive products it is well worth doing and even small savings can add up.
Take a calculator with you
You could always take a calculator with you to the shop to work out what the price per unit is. You will need to make sure that you are comparing like for like though because units can vary not only between brands but within them.
Look at the price per item of 100g
Many supermarkets will list the price per 100g for items which allows you to do a price comparison. Some may list price per item for some and price per 100g for others and this can be confusing though. Most are able to be compared though and if you compare the ones that you can you will at least be saving some money.
Take your time
If you are rushed, you are more likely to make an error when calculating which is the cheapest product to buy. We all do it, so if you can make yourself some time when you are shopping you could find that you end up saving money.
Ask for help
If you are struggling with calculating which is cheaper then do not be afraid to ask for help. You could ask friends or family to see whether they can help you out. Do not feel embarrassed as even the best mathematician could struggle to see, at a glance, which offers are the cheapest.
