If you're researching booking your next summer holiday but want some cheap travel ideas, turn your attention to this new study published by the Post Office.

For its annual Holiday Costs Barometer, the Post Office looked at 18 different European beach destinations and ranked them according to value because budget-friendly = best.

The study took into account 10 different items that you would normally purchase on holiday and added the costs up to see which destinations were the cheapest. The ten travel essentials that were look at were: a cup of coffee, bottle of beer, can of coke, glass of wine, bottle of water, suncream, insect repellent, UK newspaper, three-course dinner for two and a two-course lunch for two.

And coming out on top for the best value is a European resort you may never have heard of: Sunny Beach in Bulgaria.

All ten items bought in Sunny Beach came to a total of £37.33, approximately £21 cheaper than the next best value destination, the Algarve in Portugal.

Good news for those also wanting to book a holiday to the Costa del Sol, too, where a bottle of beer or glass of wine cost just £1.75 each. While this may seem outrageously cheap to us Brits, it is still nowhere near as budget-friendly as Sunny Beach where a bottle of beer will set you back the same as a cup of coffee - just 70p.

On the flip-side, the same 10 items bought in Ibiza (the most expensive resort) would cost £131 in total or £118 in the next-most-expensive resort, Sorrento.
