Few buyers for pricey stamped passports

Shanghai - Most visitors to the Expo may like to collect as many pavilion stamps as possible, but there are not many online buyers for the exorbitantly-priced, stamped Expo passports, which carry seals of all the national pavilions.

The price of purchasing stamped Expo passports online has increased 10 fold. A passport with 45 stamps is priced between 280 yuan to 320 yuan on Taobao, China's largest online trading platform, while a blank passport costs only 30 yuan in souvenir stores.

Statistics show that less than 100 stamped passports were sold nationwide over the past week.
