What's the single most expensive thing you bought during the sale?

Just Cause, $0.27

$5 Civ 5 Gold upgrade

X-Com: EU together with the DLCs. Around $14 IIRC

Trackmania 2 Canyon 3-pack, 24.99€.

Dungeon Defenders collection cost $16.99, L4D2 and Civ 5 Gold was $14.99 I paid for but did not keep for myself
I bought for my lady friend

I bought Civ 5 gold upgrade, CS:GO for myself

I bought only one single thing, portal 2 two pack. It was about 6.23 and for me, it costed 7€

Torchlight 2 (2 copies) for 2 tf2 keys + 3 refs each. They're not even for me, I bought them As B-Day presents for 2 friends of mine

Edit: I've just remembered that I also bought a copy of Ace Combat for me, it was less than 3 tf2 keys but I don't remember exactly how much it was.

Deus Ex: Human Revolution - The Missing Ling 1,04€. It's the only thing that I got in this sale.

For me it was monaco 4 pack.
And it was totally worth it!

Probably Dragonborn for $10. Why Bethesda is still charging so much for it (and even raising it by 3 bucks later on) is beyond me.

CS Complete @ $7.49

Fallen Enchantress: Legendary Heroes for ~12€

$30.00 Call of Duty Black Ops II.

i suppose it was football manager 13. around 9 euros

TimeShift - 15$

"Deus Ex: The Missing link". I got it by selling some tradings cards, so... technically I didn't spend anything.

Dishonored for £5.09 :)

This

Saints row :the third the full package

I guess that was Magicka, but PLUS a couple of DLCs. They all cost 7.19 Euros. But as a base game, the most expensive was Assassin's Creed Revelations Gold - 5 Euros. LoL Didn't spend more than 20 Euros...

7.49 euros for GTA 4 Complete

Star Wars Collection - 2013 44,99€
