People are being warned the cost of buying from UK based websites is going to rise from January.
Ordering 152 euro worth of clothes from the UK could end up costing as much as €236 when delivery, VAT and customs are accounted for post-Brexit.
There will be no difference when buying less than €22 worth of goods until July 2021.
Doireann Sweeney from the Competition and Consumer Protection Commission has warned people their rights to return goods will also be impacted:
'Right now you have strong EU consumer rights when you buy from a UK website, but come January 1st you will no longer automatically have these rights. This is important as EU law guarantees that you can return a purchase and it provides you with important protections if something goes wrong, for example, if something doesn't get delivered'.
