A little survey

Bump!

Isn't buying from a reseller like GMG or HB exactly that? The prices are occasionally lower than the Steam store...

Am I the only to have read the title as A little pussy? Yes? OK...

Unless you can pull something like the DailyIndieGame guy is doing ( pricing wise ) i highly doubt you can just open a store and sell stuff for the same price as steam :)
UNLESS , there is some bonus for buying from you like ppl already mentioned .

Like Humble / GMG / IndieGala etc ...

And even then , people are still kinda hard to trust a newly opened site .

It would depend on the regional pricing. A lot of resellers sell their games in USD (I believe Bundle Stars is the only exception that has a CAD conversion), so for me, it's cheaper to buy off of the Steam store most of the time.

If you're also interested in reselling Steam games, you would need some sort of guarantee like more reputable ones have, if you want to gain people's trust. IG, GMG, HB, etc. all have a great support system where if you are issued a duplicate key, they will send you a new one.

Were you looking to set up deals with developers to sell their games through a site you made, or are you just looking to sell off extra keys you've earned from bundles/sales? If it's the latter, you may just be better off trading~

clickbait T.T

I noticed that Valve just added a new rule recently, Review ratings only counts from reviewers who bought the game directly from Steam. So buying directly from Steam store if you want to contribute a review/vote to the final rating.
Other than that, I see no point buying games which more expensive. I'm not rich, so lower price is always better. No matter where, but must be from a trustable place.

potato!
