Переведите текст срочно нужен. Secondly, more and more supermarkets supply customers with trolleys instead of wire baskets: their bigger volume needs more purchases. One picks up a small item, say, a pack of spaghetti, puts it info a huge trolley and immediately feels awkward that it is so small. He starts adding more. Thirdly, all products are nicely displayed on the racks and of the look fresh in their transparent wrappings with marked prices. A normal person cannot ignore attractively packed goods. And so one cannot but feel an impulse to bey. And, finally, supermarkets don't forget about those who look for bargains. The so-called "bargain bins" filled with special offers wait for their victims. No one can tell for sure if the prices are really reduced, but it is so nice to boast later that you have a very good eye for bargain. So when a simple-hearted customer approaches a check-out, his trolley is pilled high. Looking at a cashier, running her pen over bar-codes, he starts getting nervous while the cash ragister is adding up the prices. And, getting a receipt, he gives a sigh of relief if the indicated sum does not exceed the cash he has. Of course, one can give a piece of advice to the simple-hearted: compile a shopping list and but only pre-planned goods. The daily shopping route of some housewives includes visits to the baker's, butcher's, grocer's, greengrocer's, fishmonger's and a dairy shop. In the end of the route their bags are full of loaves of bread, meat cuts, packs with cereals, fruit, vegetables, fihe and dairy products.
