We get a confirmation prompt when buying certain items from vendors, in order to prevent us from accidentally wasting a few Source Marks, or whatever. How about the same courtesy could be afforded when spending 5k Quarks = 20k SM? A single accidental press of a button can waste months worth of grinding.
I agree. All purchases should have a confirmation prompt, that requires an actual click by the purchaser, before going through.
I'm generally a 'be careful when buying' kind of person...but as the game DOES occasionally hang or glitch out, a mis click is very possible...so yeah. On this very expensive vendor...I'd say yes. Seeing as we can't donate a modded item or one in our armory setup without a confirmation...something that at worst costs us 1 piece of gear...this seems a reasonable request.
