Ordering off the Internet - Vietnamese site

There are of course bookstores that sell vietnamese books on the internet. When I found this site Vinabook.com, I had to make an order. The only problem is that it is hard to decide on books online, especially when you're barely reading as I am. Google translate helps, but sometimes the translations leave much to be desired. It would be so much easier if I could just look at the books. Also, the shipping costs are pretty high, since books weigh a lot. The good thing is that the books are so much cheaper. So even with the high shipping, which essentially doubled the cost of the books, they were still cheaper than the bilingual books I was buying from Amazon. The other problem was that to make the shipping reasonable, I didn't use air mail but ship mail, so it took a while(maybe a month or so) before I received the books. You need to plan ahead at that rate!
