Where do people get all these game gifts?

oh man someone is going to love teaching you :)

Edit: Maybe

Different countries have different prices based on their region. that greatly affects pricing of particular games, also when theres mass errors when people pick up games like dark souls or that haileen game that got greatly reduced it will get sold real cheap. people will jump on those exploits and put lots of them into their inventory to trade later when the want for the game is high again. Also when people buy games from bundle sites they may trade those for steam gifts if that is what they prefer.

win or buy + bets

we sacrifice little kids and gifts appear, its magic

...from steam seasonal sales, coupons, bundles, and trading.

They buy these games discounted and/or from cheap regions. Then can then trade these gifts at any value situated between the full US or EU value and between the price they originally got it for (which can be ridiculously low when it's discounted and from a cheap region).

Is there demand for these gifts, and why won't people buy these gifts off the store themselves ?

↳ Let's say I want to buy something on an impulse (like i recently did with Mount & Blade : Warband), I might not want to wait for the next sale. Suddenly, there's demand for whoever has a Mount and Blade gift in his inventory. So, I browse SteamTrades and find someone who sells it for 1,5 key (2,6€).

Even if I had not suddenly wanted the game on an impulse, and waited for a -75% discount, it would still have cost me 5€ since the full price is 20€ in my region. If the guy got it from the Russian store at -75%, it cost him something like 87,25 rubles (1.32€). Here's how he invested 1,32€ and got the double.

That might not seem like a lot but now, multiply to all the people who want a slice of the cake, and all the people who, like me, won't buy in their region since they can get the exact same things much cheaper from traders.

It is an example of Economic Arbitrage and it is in response to developers/publishers practicing Price Discrimination.

it's called small profit

Your head doesn;t work?
Here I will explain this to stupid people. Well you have to buy them(games) in steam store as gifts. Then you get game gifts in inventory.
If you buy game for lets say 5$ and sell it for 8$ , yeah i don;t see a profit here, because it's so stupid, you loose 3$ (5-8=-3).<-- see -3$.
Well diffrent regions don;t have the same price. (like say game x in USA is 50$, but in Europe it's 50 euros). euros=dollars.
Well as 7 million people live on this planet, it doesn't really matter, it's not like 7 billion people live on this planet, lol. Not that many people who would buy games, only 7 million people on this world. There's not even internet in Africa, so 1 million off.

They buy them or trade them with someone else. After it the gifts sitting in their inventory and loosing value or became almost untradable because will appear in some bundle or amazon for the price of few cards etc. They hope to some game will be removed from steam steam to rocket boost the value what will compensate the losses. :D
