i think, just a suggestion the best way to purchase something is for lowyat.net to be an intermediary and certify buyers through very simple process such as Paying into Lowyat Bank Account, and then when the ammount is reached, then the amount can be realised.

Now information that lowyat.net would need and keep confidential, would be source of product , and that can also be confirmed with a little admin fees, such as calling and checking whether it exist. and there are much more different approch to make it 100% safe. Trust is another thing entirely compare to Honesty. if you get what i mean.
