As part of its 14^th annual holiday money report, it found that 85% of its 40 bestselling currencies are currently weaker against sterling compared to a year ago.

This means UK holidaymakers will benefit from cheaper prices when buying staple items when overseas, though the report doesn’t include information on travel cost to the destinations.

It looked at the cost of paying for eight consumer staples when abroad: a three-course evening meal for two with wine, bottle of beer, glass of wine, can of Coca-Cola, large bottle of water, cup of coffee, suncream and insect repellent, and found that it had fallen in 33 of the 42 worldwide destinations surveyed.

Post Office Travel Money said these goods were cheaper by over 10% in 11 destinations.

The biggest price fall of 44% has been in Antigua (£70.51), while in Europe, Corfu has seen prices slide 21% to £75.91.

Prices have also plunged by over 19% in Darwin, Australia (£118.96), 18% in Singapore (£98.85) and Jumeirah Beach in Dubai (£126.30).

Overall, Sunny Beach in Bulgaria came out the cheapest for the goods, at £30.68, having fallen 15% since last January. It’s also 30% cheaper than runner-up Turkey where prices in Marmaris (£44.15) are down 2.4%.

On long haul destinations, Tokyo has come out on top while Vietnam has overtaken Bali for holidaymakers wanting a beach holiday.

At the other end of the scale, Abu Dhabi (£152.11) and the Seychelles (£165.10) remain the most expensive destinations to buy the consumer staples.

Post Office Travel Money Head of Travel, Nick Boden, said: “With the price falls we found in destinations worldwide, holidaymakers will have plenty of choice in the coming year – provided sterling holds its value.

“In Europe the best deals are likely to be in Bulgaria, Turkey and Portugal, while further afield Japan, Vietnam and Bali are looking good bets for the bargain-hunter.  The clear message is that holidaymakers should do their homework on resort prices before booking to be sure of the best deal.”
