hi bart,iam from indonesia also :),yes the buying process took me nearly 1 weeks to process as iam using wire transfer,my process was :
1. Order through share it and choose the option pay though wire transfer
2. Do the transfer on my bank(BCA),if i not mistaken 10% is their fee,not including there is extra deduction from local bank in conitec's country(germany)if i not mistaken it's around 50$!,make sure to tell your bank about the EXACT value that you want to arrive at conitec's account,normally the bank just pre-assume you know about their fees and bank's beneficiary deduction.
3. Scan and e-mail the transfer receipt both to conitec sales e-mail and share-it e-mail.
4. Wait for verification,normally tooks more than 3 days to arrives.

my best suggestion is through credit card,yeah before you make the transaction you need to ask the bank to allowed the transaction.

about game publishing check the "Game Business" subforum,there was so many discussion about these.
