I would like to have an increase in the premium duration of SMS Payments. With 'Credit Cards via GW', 'Resellers', 'BTC', I could have 30 days of premium with USD$9.99. But with SMS, I could only have 8 days of premium with USD$8.56 (converted from SGD to USD). That's almost 3x the amount of duration I get with almost the same price. :(
