export US products to the UK.. is there money in it?

Hi everyone, im new to the forum and the lovely United states. So my idea is to export such items as shoes, sports jerseys and food to the uk just to make some extra cash on the side. You might wonder why food but a box of lucky charms sells in the UK for around $12-$14. Now the fashion side of things is what i think could make some decent $$$, as people in the UK always want shoes that are only sold in the US and are willing to pay the extra fee. so my question is does anybody have experience in this filed and is it worth it due to the import tax you will have to pay?



Thanks
