drm-sck: Real question here: Why people are still using Paypal with how much they're charging for transactions ?
Guess they are not even the record-breaker. In many cases transaction-costs of up to 10% is a usual case. A customer may not see much of it until a merchant is "charging them" for the additional costs. I guess lowest merchant-fee is about 3% and highest can reach 10% or even more of the "goods value", dependable on certain factors.
Paysafecard is probably with the highest transaction-fees, although, this method seems to be the most secure one, so there is lesser hassles by buyer-disputes and whatelse, finally leading to losses on both sides including admin-costs which are always huge. Another advantage is that they may not debank the sales of "forbidden games", so even lesser hassles on both sides. No matter what game, the publisher (or shop) may always get their money, so i guess "safe" is a good word for it.
Paypal is rather expensive as well, they may debank certain games and it seems they are not the most reliable method.
Credit Cards are probably cheapest, for a merchant at least,... but they offer lowest security and can lead to a lot of hassles. They may debank certain games, another "hassle factor".
