online store suppliers

[rad70]

Hello everyone,
My first post here
I want to start new small project selling retail electronics online ( like memory cards, hand phones, digital cameras, computer cables, ..etc) .
I'll sell only to customers outside Singapore .
In fact I know how to sell but I don't know how /where to buy !
And my questions are .
1- From where in Singapore can I buy at wholesale price ( export sets ) ?
2- Do I need to pay 5% GST ? and if so can I get it back providing proof that those sets sold to overseas customers
Thank you in advance for your help
