Whats a rough kind of price range of cost to sell soft drinks on Amazon UK from Spain?

Hi, I’m looking at the idea of selling a few soft drinks on Amazon UK and I would be able to package and take them to a post office or something to send them from Spain, I’m curious what kind of costs are involved from Amazon and from shipping based on the weight and distance with it potentially being 330ml cans and/or 1.5litre bottles of liquids from Alicante, Spain to England but I know it would likely vary a bit depending on where in England, they wouldn’t be my own they’d just be brand drinks that aren’t easily found in England

Thanks in advance for any help 🙂
