I don't see the problem with Grey imports... actually, can you still get "grey" imports from the EU now that it's supposed to be an open market?
I can understand prices being higher in the UK due to tax, retail space being more expensive, workers and transport costing more etc, but if it can be legally imported from abroad for cheaper, then we should be free to do that. Obviously we end up losing things like warranties and trying to return an item bought off eBay is either impossible or at least a lot more difficult than if you bought it from a UK retailer.
So, leave us alone, we should have the right to buy our imported goods for a lower price if we're willing to live with the downsides of lower cover on warranties and returns.
