Cannot complete the purchase of 6 items. After pressing "Pay in USD" then "Confirm purchase" nothing happens. Tried several times.
In-game or using a web browser? In-game you have to make sure that steam overlays are enabled in steam's preferences so the purchase can be processed. It will open a pop-up asking you to authorize payment via the steam wallet and this doesn't pop up if the overlays are disabled.
Thanks for your help Christian! Yes, I tried to purchase in-game. I'll check if overlays are enabled. Edit: Right, overlay was disabled. It works now, thanks!
Well there's a time for principles and there's a time to grab a deal, so back to owning all content - not counting some liveries. Looking forward to giving the X-bow a spin.
