I was in Forex (you know, the yellow "exchange shop") the other day to exchange some foreign notes I had, and out of a whim I asked if they exchanged the Vietnamese Dong...and they do! She said that they can't always get it, but if you order they try, and sometimes they have it in stock when somebody has exchanged it for SEK.
So you don't have to buy it on the net!
I don't remember exactly but it was 435 or 465 SEK for a million dongs. I don't know the price at the dealers or Ebay, but may be cheaper at Forex too? Much easier anyway!

Ps. What IS the price with dealers?
