Tricks of sellers  

Probably everyone has been perplexed after coming home from the shop and founding unplanned and even unnecessary things among the purchases. To avoid such kind of purchases, you should be armed with some knowledge which maybe will protect you from appearing of unnecessary things at home and certainly will make sense for you in different kind of tricks used by sellers. So let’s start!
Apparently, when first supermarkets and big shopping carts emerged, we thought – at last, evolution is here! However, it has some kind of trick. Because of large blank space some discomfort might come out and customer would like to fill in the unfilled space. In a result, instead of two packs of juice we push a full shopping cart in front of us.
Most usual and often purchased products, such as bread, milk and cheese, are generally placed in the farthest corner of the supermarket. It’s easy to understand why: these goods are cheap and necessary for almost everybody, so they are put further, to force buyers to pass many shelves with other goods and drop some unplanned products to their carts.
Time after time sellers change product places to prevent the routine of shopping in the supermarket. Besides, going through the labyrinth of product shelves, buyer might see something new and, maybe he would like to buy an unplanned good. Because of the same reason, product pack is very important. It must be tempting, bright and attractive.
It is easy to get on different discounts and other benefit offer tricks. Offering you to buy 2-3 products together and get a discount, the only shop’s aim is to make bigger profit, practically, to force the customer to buy as much as he can. And they certainly do not want to bring pleasure for the customer or make a charitable action.
Sellers also tend to influence your eyesight – average person blinks 32 times per minute. Special lightening in supermarkets can cause you blinking up to 14 times per minute, and it’s quite rare comparing with the normal blinking period, and that can bring you to the condition which is very similar to the trance. 
Mirrors in clothes shops are created not only to reflect your silhouette, but also to make you confident about the way you look. And what else can change you in a good way but the beautiful things that hands are stretching to grab? Mirror in a fitting room is the best adviser? However, you should remember - in many shops such mirrors are installed, that make you slimmer.    
One more curious fact – it occurs some clothes shops write size on labels smaller than it is in reality is to make customers think, that they wear smaller sizes. So next time you are happy about the new dress bought with one size smaller you usually buy, check up your weight using scales and if you haven’t lost some kilos then , know – it is a trick of sellers. 
The important component of influence to the customer is aroma marketing. The thing is the way how human brain gets information about smell is much shorter then hearing and visual ways.  It was confirmed that groceries shops use smell of cucumber and watermelon effectively. Furniture sellers use smell of coniferous trees. In boutiques smell of leather and expensive tobacco are best to be appreciated by customer. Lingerie and wedding dress shops usually use scents, which stimulate romantic feelings bringing to the euphoria. These smells usually are unclear and not realized.
At last, happily having evaded from all temptations, departed from different barriers and standing at the cashbox - don’t hurry up to relax!  On your way to the cashier many small things, such as chewing gyms, newspapers, sweets, batteries, are warning you. On one hand, boxes with such kind of products are very useful, on the other hand – it brings you to the unplanned money going out. The point is that the product price near the cashbox might differ from the price in the selling hall and difference is turned to the shops favorable side. 

And remember, shops will never work to their own loss and they will not go in for charity. Save your money!
