Let's make money with low overhead deposits on CEX.io?

I've been using prepaid debit cards for CEX.IO deposits but there is a lot of overhead. Anyone know another way to get fiat in to CEX.IO with no or less fees besides storing complete bank info on their servers?

I found prepaid cards at a local store with the lowest activation&reload fee at $3.00 and no transaction fees except for ATM withdraws. Then on the CEX.io side there is the 3.5%+$0.25 fee for CC deposit(3+0.25+400+((3.5*400)/100) or $17.25 to get $400 deposited). We can't get past the CEX.io side unless we store bank data on their server or lose more money through crypto wallet transfers; ewww. Looks like we're looking for even cheaper prepaid CCs or some crypto currency deposit flow.

Sorry if you don't like CEX.io. I tend to only trust my money with crypto currency sites only when they have a history and it's not a wreck.. I also like the UI/UX. I still don't store persistent data on their server.
