Summer Sale purchase problem

That's an awful lot of money, i think large orders might be causing issues as almost noone probably does it and the checkout isn't really programmed for it but it's my guess.

And no if something goes wrong, steam does not give you a discount after summer sale.

if the order has gone through contact support, they are currently investigating why I didn't get a summer sale card on my last purchase even... they will definitely look into why games weren't given and money is taken.

Could be avoided when people didn't prefer to make their purchases on the first and/or last day of the sale. But that would go against all that makes us human ig.

From what I understood you attempted to buy over a thousand items at the same time and the system hard crashed, billed you the full amount, and gave you none of the items? Yeah you'll need to contact support to sort that one out, I wouldn't be surprised if you just pushed their system well beyond what it's intended to handle. No clue if they'll reimburse you the money or give you the stuff you bought tho.
I guess in the future try to not buy that many games at the same time just to be safe, spread it over several transactions if possible.

Have you received any emails in your email, like about a purchase/order or something?

Any idea what "CEDAR - VOH CE" is and why its tried billing me almost $7000 for it 16 times now and counting? It shows up as failed on steam

You have 72 hours to try and repurchase a failed purchase, I remember seeing this message when I last had problems. I don't know if it only happens on specific errors, but I am sure it still exists at least, whatever the requirements are.
