They're not all shit, it just takes a bit of digging (pun-intended), I only suggested indiegala because its another cheap alternative, usually with generally decent games. Everything else takes searching or requires you to already be buying from the site anyways and just dropping the leftover keys here without checking games...80% of the bundles on DIG usually have 1-2 decent games, maybe one actually good game and the rest are throw around keys, we add them but we also just usually throw a ton when we do it to clean out the lists we already have.
I usually send them here when I have nothing else and they are already in my stock here just to give "something" back, pos has like a decade long list hidden somewhere or something lmao and gives tons of keys anyways of all sorts.
My point being that just buying them as single bundles to donate here would likely end in the result of trash games.
I'm not sure how familiar you are with indiegala bundles if you didn't know about DIG, but they have a buy two get one free deal almost always when you buy at separate times, 3 if you buy during a day one bundle which is called happy hour.
Fanatical also has some decent cheap bundles ranging from 50 cents a game to even lower when you don't choose the games almost at all times.
Again, its not something anyone can choose for you, all I can say is purchase by purchase DIG bundles without finding a good bundle wouldn't likely be great additions, but thats looking at it from the person who would be on the requesting end as well.
I'm just throwing out some likely close to the same price alternative options that are less trouble than searching all the dig bundles by hand...I've tried that, its not fun
