This is a perfect chance to test you haggling skills. Because HCMC is heavily touristy, the market sellers here have adopted the technique of over-pricing everything by 300-600%, so even if you do haggle 50% off the price, they are still ripping you off, and making a huge mark up. With so many market stands offering the same stuff, you can offer ridiculous prices to gauge the value at one stall, then move on to another to if they don't except. Remember that there are more stands than there are customers, and the simple walk away technique will almost always work. Regardless of what you pay, the owner will always make money. (t-shirt pay no more than $2, some places will try charging you $10)
