The annual summer sales period opened in Greece on Wednesday, and will last to end-August.

In a bid to rekindle movement on the market, following a slump in turnover in the last two months, retail shop-owners are offering discounts of up to 70 percent.

Merchant and consumer organisations said the sales period was an opportunity for purchasing top-rate items at bargain prices, but advised shoppers to buy wisely, focusing on their real needs and comparing quality and prices, and to not be carried away by flashy advertisements.

The Development ministry’s general secretary for consumers, Yiannis Economou, warned shoppers to buy carefully, keeping their family budget in mind and without excessive use of credit cards.
