Thanks for the info george, however the modus operandi of such con that i have encountered is more or less such as yours.
That payment is either by bank or wire transfer. This happened to me before, so pardon my french for not being enthusiastic about your MO.
Long long time ago, this happened to me. After I had transferred money to the 'person' in Romania and after he/she 'proved' in a way that 'invoice/receipt' was in order pertaining the item that i'm interested in purchasing (photocopy by email), the contact vanished after saying that the item was in delivery either by TNT / DHL / UPS etc..i opted for DHL.
Mind you that i was naive back then and learnt my lesson. Talking about GBP 800 worth of experience!!!

.
So please convince me by saying that you have customers here in Singapore or anyone that have used your service and have the product in hand which i am more than happy to view.
I stand corrected if you say that
1. you dont have customers/clients yet from Singapore
2. others already purchased and happy (anyone from M'sia/Asia/Singapore/Indonesia?)
3. you have a specialized customized product, meaning that your clientele is small.
4. I can refer to someone BY email or somebody FROM your own country.
5. you can't match other big company OR
6. you havent established any corporate/merchant account with Visa/Amex/MasterCard.
I prefer to do business either by paypal or credit card. One of the reason that i frequented B&H in new york. So far, items ordered arrive on time and refunded if i'm not satisfied.
thanks george

and again pardon my french for being cautious..
