Back when I first went, in '96, it was bargains galore...pretty much everything was cheaper than over here....nowadays, with the advent of Internet shopping and cut-throat competition brought on by the power of the supermarkets, the bargains in Florida are tougher to find.
Definitely NOT cheaper now are Digital Camera's, Camcorders and Laptops.....all of which are near enough the same price now in the UK (more so digital cameras, which dont attract import duty). I wouldnt buy any of the above in the US now, not just because they arent any cheaper, but also from a warranty and ease of return should they develop a problem. (I read from time to time that
walmart goods can be returned to asda, but ive yet to see anyone actualy do so, is this an urban myth ?).
Sportswear can be cheaper if you go to the right place (ie not Footlocker). The outlet shops for Adidas, Nike, Reebok are all pretty cheap, but then we have similar in the likes of Freeport in the Uk, and I would say the main advantage now is the ranges tend to be newer over there. I normaly don't buy stuff over here and buy a years worth when I go out.
Video game consoles are pretty much always cheaper over there and often released earlier than the UK, such as the Sony PSP. There can be regional issues though.
