Sellers Offer Free Samples
Pass by the numerous trays of free samples that you can bump into at supermarkets. You will be less tempted to buy the product if you do not taste it. Unfortunately, post-sample purchases are very common.
Solution: Do not go shopping on an empty stomach. Eat something first. Hungry customers will always buy more food than they would if they were not hungry.
Sellers Use Creative Lighting
This trick is used by all sellers. The right lighting makes food look better. People get attracted by fresh-looking and bright products. Meat, fruits and vegetables that look as if they were brought to the store a couple of minutes ago are hard to resist.
Solution: Take a close look at the food you are about to pay for. Find different, more natural lighting. Avoid the faux glow and see if the product is really fresh.
