I doubt that it is cheaper than any other websites out there, because the operators absorb most of the saving they get from fees and do not pay it forward to the clients in offering cheaper rates. It would have been great if they did a comparison somewhere to proof this statement. It would attract a lot more people using these services. They could offer discount to people paying with Bitcoin. This will only work, if the site accepts multiple other payment methods too. < If I paid with say, CC and I see someone else using the same sites, and paying less with Bitcoin, I would start using it too to cash in on those discounts >
Hope to see this happen on some sites soon, let's push adoption with Bitcoin discounts. ^smile^
