Wurzelkraft: Good news indeed. Do you know any DRM-free shops with flat pricing?
A better question would be if how many flat pricing shops of any sort do you still know. I'm just at one, ShinyLoot, but that allows DRM for part of the catalog. Otherwise, what Grargar said, only other DRM-free ones I know of are also DotEmu and FFG, but DotEmu applies standard regional pricing on all titles and FFG adds 25% (saying it's VAT, actually Swedish VAT) to price for EU purchases.
mrkgnao: I myself also don't make the distinction that IAmSinistar makes. For me, it's either flat priced or it's not. I don't believe in regional-pricing-lite.
I'm very strongly considering removing one distinction from the way I track... In part also because it's a pain to keep track, but was uncertain about it from the get go. So thinking of no longer caring whether a game regionally priced in (part of) EU (or NO, or CH) or AU is also more expensive or discount only and just caring that it is. So it'll be RU-only (including UZ, as it usually is), RU/UA/BR (usual suspects for discounts), or anything more than that. After all, it's a matter of the extent of regional pricing, not how it's used.
