Went online today and saw Payday 2 on sale. Been waiting for it forever so naturally I go to buy it. The store is incredibly unresponsive, took nearly 20 minutes of trying over and over again before it finally loaded all the needed pages and let me buy it.
Then I decided to get the DLC's just now whilst they are still on sale. I've been trying on and off for an hour now and it keeps failing at various stages because the store just stops loading and times out. Finally got to the last page just now and it died again before I could complete the purchase.
Only started using Steam properly recently but if it's always this bad, I can't see why it got so popular. Haven't been able to connect at least 4 times this week due to server problems as well.
