Hi Belfastgal,
Just a few points -
1. Could you be a little more specific in defining how Ebay UK just isn't the same as Ebay US for that variety? are you talking about staple goods? or more obscure items?
2. Heads up - many products now originate in China and/or other far flung places, they get shipped halfway or more around the planet before touching down in the geographic US. Shipping an item over the pond really isn't such a big deal. You also get strong packaging and good insurance cover to protect you/the item.
3. Customs/VAT - There is always some duty due on good imported into the UK - rates and amounts do vary, as well as some excemptions etc - take a look at the HMRC website for more info on products you may wish to bring over.
4. The USA enjoys (overall) the best pricing in the world - theres no doubt about that, the UK is in all essences a pretty small market, small enough that some exporters don't even bother 'wasting time' selling to UK importers/Businesses. That's the reason for 'less choice' here. You mention a jacket which when added with the VAT and customs charges and shipping make it expensive - I bought over a 2003 F150 Harley Davidson truck and with all the charges and duties worked out a good £15,000 cheaper than buying here. Depends on the product, the demand and the pricing.
5. As already mentioned, your in Northern Ireland and post/shipping charges are higher - something you've got to get used to !
6. Sometimes it can be great to shop as if you were in the USA, get items delivered to a family member and then next time you are over you pick it up. 'Generally' these tend to be more high end/esoteric/high value purchases - most 'normal' type purchases you can do locally.
I'm a Ebay power seller, and also trade internationally (mainly US>UK and China>UK) so it's interesting to me to hear consumer type feedback such as this.
Lastly - shop around for the best shipping deals and email sellers directly if they will ship internationally as a one off after you provide more ID etc. I do this all the time with US sellers and only a few have refused, the other's have done it, even though they say 'US only'
