... oh, well, sorry. I am being unfair and had it not been for this info I had known nothing about this. You are not to blame here really, its all LGP.
It just pisses me off that I used my card on that site assuming the little certificate lock symbol in Firefox would indicate it to be as safe as any other shopping site I visit, though looking a bit dated in this case. Normally I buy all my games from TuxGames and have never had a problem so I plunged in here as well. I guess VISAs online reimbursement policies are more focused on scams than poor code so I better contact my bank for a new card.
I do not remember if the SSL protected part of the checkout was only LGP or if there was some other company collecting and protecting the info. Am I right to assume that someone could have collected all my info, despite the SSL connection itself if they own the page?
Well, it is really no biggie, but still. I wonder how many people purchased something and ho many of them that will stumble across this thread.
A very easy way would be creating for example a shop inside amazon. Then the money transfer would be also save enough. I don't think that website encourages to buy linux games. The default prices are way too high for such old games, also a price should be in € - like most europeans use not the currency that only 1 country with high inflation rate uses.
