Consumers who shop in different supermarkets to keep costs down end up spending more money, news agency ANP reports on Thursday, quoting new research.

The research, by economist Marc Vroegrijk, found that 60 to 80% of people shop at different supermarkets in search of bargains.
Vroegrijk found that although consumers bought individual products at a lower price, exposure to the other wares on sale meant they ended up buying more than they would have done on a visit to just one shop.
