Overview: SAIGON, VIETNAM: Having truly struggled to spend $100 US in an hour in a Sri Lankan market last year I thought $200 would be tough in Vietnam. I was very wrong! The Dongs ran out fast and I didn't even make it to an hour. Spending 5 million Vietnamese Dong in less than an hour shopping at Saigon's old market was awesome. But I wish I had brought more money as I didn't even get through 20% of the market and I felt I could've gone shopping for at least another hour. So therefore I cam up with the $400 US (10 Million Vietnamese) Saigon market hunt challenge. The goal was to shop for 2 hours....
