Firstly, if there is anyone local please review and correct anything I put down here, I am dealing with the German market for a while but I am not there.
As for the percentage - I assume It's not very low pct. of people, but most of them are just lazy and like to use alternate options, I suppose 50 pct. of people have credit cards, plus if you have CCBILL in place - with DirectdebetEU and DirectPayEU in place, you should be more or less covered.
It makes a total sense to have a site dedicated to German Traffic, from a couple of reasons:
1) tours have to be soft, nothing that's not behind a certified AVS system can't show anything hard
2) now there is many versions of this, and I would like someone native confirming this, BUT
I suppose if someone in Germany promotes you or if you advertise in Germany - payment options should be certified by authorities - which in fact means, if you want to obey these rules you are not eligible to bill with the regular third party biller and if they decide so, they can as well ban your site, as happened recently
What I could suggest, is to team up with
CASH DORADO - paying 44 EUR per sign up with their flagship Fundorado.de and it's a busload of money.
Their site is probably one of the top elite programs worldwide, just at the moment still suited especially for German traffic (Stefan please correct me if anything)
Another mega site working very well with German traffic is:
MOMO NET network from Switzerland
Behind this weid looking name, you may find a variety of sites that work very well with the German market, one of the top players on the market.
From the other stuff, I could suggest to check also the
PRIVATE CASH with a very well recognized brand name in German speaking countries or
PAYSERVE with great niche sites and using
VXSBILL that should be able to convert local cards as well.
Apart from that, we will be launching our program within a month or so and our main market is still the German speaking, with more than 8 mainstream TV reports about the concept the brand is widely known and I will be more than glad to hit you up once we are set.
Hope this helps a bit.
