Sino, I agree that often people have to buy some items from abroad, usually the US, UK or Germany, but there is a need to try and encourage local suppliers to stock items.
Better still try and get a better relationship between the users, retailers, importers and manufacturers, so that if we want to order an item not imported, or out of stock, it can be sent direct to the dealer, bypassing the importer. This system works already in the UK, and I think is being rolled out in the US, by Ilford.
It's a chicken & egg situation forced on us by certain dealers/importers, who have lost business through there own poor service to online retailers in other countries.
