There is a grey market in electronics in which retailers import merchandise from regions where the prices are cheaper or where regional design differences are more favourable to consumers, and subsequently sell merchandise in regions where the manufacturer's selling price is more expensive. Online retailers are often able to exploit pricing disparities in various countries by using grey-market imports from regions where the product is sold at lower costs and reselling them without regional buyer restrictions. Websites such as Taobao and eBay enable customers to buy products designed for foreign regions with different features or at cheaper costs, using parallel importation.
