Just a word of caution. Although the prices for ipd internationally may be better than say New Zealand you should also check out the freight and shipping charges. What's the point of getting cheap ipd prices which are then converted to very expensive ipd prices when the freight is added.
Do the numbers add up when freight is taken into account? Our research on many products, including ipd, has revealed that many suppliers are now offering ipd freight free. This will change the numbers in your favour.
