I won your promotion and could not claim any of the prize because I could not buy any bitcoins...
I hope my suggestions help as I would've bought 1 bitcoin right away if I could have...
Here are a multiple of payment methods:
Western Union and Money Gram: Both have someone send money to your country and a name you provide. You go to your local store and get cash in hand for their sent payment. Generally the money is available in 5-10 minutes. This is an awesome method for some countries as some countries it only costs $8-$10 to send up to $1000 to someone in. However, US to US customer, generally the fee is 10% whatever you send which can get costly quick. Just a suggestion.
Another payment method is PerfectMoney.
Perfectmoney is similar to paypal and other systems but the payment is irreversible. I don't know the full details of the currency but it looks similar to the benefits of bitcoin.
For paypal, to prevent claims and chargebacks, some sellers have required buyers to click "file a claim" on their payment and then click "claim resolved" or "cancel claim" to remove the option of filing a chargeback claim. However, one could still call the credit card company and chargeback.
Another couple of options you might want to look into is OKpay as I hear they are another payment option people use. Bank wires could also be used but obviously delay time would be required. My strongest suggestion would be to look into Western Union and Moneygram. If you're in a country where the fees are only $8-$10, this could be a big payment option for you guys.
Hope I've helped and good luck with your business. Look forward to any future promotions you guys have.
Thanks a lot ! and apologies for not winning with us, we simply can't accept other payment methods as of now due to security reasons and fraud.
WU or MG: we considered this option; however, we promise to deliver bitcoins after 30 minutes of confirmation. Moreover, we really don't have an advantage here over competitors doing the same.
Perfect Money: If you could give us a little more details, it will be great !
PayPal: its always a NO NO unless its a local resident, it attracts way too many scammers !
OkPay: No Advantage ! they might as well buy from exchangers.. such as BTC-E
Generally speaking, our target market hasn't been the US as it is relatively easier for them to get hold on bitcoins through local meet ups, exchangers, or linking bank accounts to an exchanger. But we still want to make it available.
