Although they have traditionally started on July 1, summer sales are already beginning to be noticed. Some stores have chosen to advance their discounts to invite their customers to make their purchases and get the latest news at the best price.

However, "online shopping trends are producing a growing seasonally-adjusted demand on certain products", as revealed by the latest study, whose results show how the acquisition in winter of certain typical summer products such as swimsuits, barbecues or fans can be a considerable saving.

In this way, the people who bought their swimsuits in January paid an average of up to 37'65 Euros less, “which means a saving of 128%” compared to doing it in summer. Barbecues, on the other hand, reach their minimum price of 98 Euros in December, with a maximum of 193 Euros in April with the arrival of good weather ("a price difference of 97 %").

Other products that reach their maximum price in August are camping furniture (82'99 Euros) and the minimum in January when they do not reach 50 Euros. Another recommendation that they offer from the price comparator is to avoid buying a fan in August "because its price reaches maximums in full heat: 205 Euros." On the other hand, buying it in early summer, in June, can save up to 95.5% of its usual price.

Our study has also analyzed demand trends during summer sales, concluding that those over 65 are still waiting on July 1 to look for their offers, with a demand increase of 128.89% throughout non-sales. "This is because, despite the liberalization of the sales periods in 2012, the most veteran generation continues to be much internalized that the best discounts are still found in the traditional dates of July and August," they argue.

“On the other hand, millennials prefer to search for offers online throughout the year and not especially during the official discount period, since the demand in the 25 to 44 age group falls by more than 50% in the sales months "
