As end of March is slowly approaching, could you point me in direction how to find games with wallet funds (Fair Price Program) more easily, so I can buy them, gift them to zeogold or in giveaway.

It might be the fooliest decision of my life, but I preordered the Premium Edition of AoW: Planetfall (+9.5 € in Wallet funds). I'm still tempted to preorder We, The Revolution (+2 € Wallet Funds) but I will wait till day 20th or so to make any decision about it...

Well, I tried browsing the store, but prices aren't shown on list view, but I just switched to grid view & now I can browse better. I believe any games enind in .99 will be part of FPP.

Caligula Effect Overdose gives 5.90eur. More if you opt for the DLCs.

As FPP is region-based, it will be different for every user and thus difficult to find. But you're probably right, as games costing other than XX.99 will probably have their prices directly converted from dollars and are unlikely to suffer from rounding up.
