When is the cheapest time to travel to Europe?

Shopping is the cheapest time of the year at this time. During Christmas, basically all brands and shopping malls hit the lowest price, but the prices of air tickets and hotels are generally much higher than usual. So if you want to go shopping at the lowest cost, it's best to do it in mid-September, or in late 1 month or mid-April. Because it is much cheaper, and there will be many discounts to avoid tourist hotels and air tickets, shopping malls will also greatly reduce prices and discounts in these seasons. So these are the most appropriate and wise times.
