To save on International listing fees you need to list directly on the foreign ebay site..eg ebay.com/ebay.co.uk
This works out cheaper then the eBay.in international fee and gives you greater exposure.
It works out best if you open an ebay store on the foreign eBay site. Then you can list at low store inventory prices and just use auctions to direct traffic to your eBay shop.
Unless you are listing a large number of items, I dont believe its worth paying a trading assistant. Just spend 1-2 hours a week or less if you are using turbo lister. Once you get started, it gets much faster.
