Here are some points buyers look for in a good supplier:
1. Contact details - the supplier should have a landline number and a physical address published on their website, not just a mobile number that can be turned off. The email address should also be domain based email address, not the free Gmail or Yahoo ones. The idea is to be able to track down the location if you need to make verification and somehow have an assurance that this supplier physically exists.
2. Number of years present on the net. This can be checked via Link hidden: Login to view Basically the longer a business has been operating, the more trustworthy it is perceived. Two years and above can be a safe standard.
3. Payment methods - there must be safer way to pay than Western Union. Paypal and credit cards provide a chance for buyers to file for a dispute / charge back should any issue come up. And that would be a lot better than being helpless with a cash sent through Western Union. You will notice that there are some China based suppliers that claim to accept PayPal, but when you try to order and pay/check out, you will see that it asks for contact details, probably will then be requesting you to send money using Western Union.
Hope this helps. :)
