TheCoop: Well this is a bummer. GOG is now charging sales tax on purchases for US buyers (or at least, US buyers in my state), after quite a few years of buying the games at the listing price-only. Hell, I just bought Mad Max and the The Evil Within bundle a few days ago without sales tax, so this is obviously a very,
very recent addition.
Atreyu666: Isn't it normal to pay taxes for purchases? When I buy stuff from Amazon, etc, I also have to pay taxes...
Not that long ago, online purchases didn't charge sales tax on a lot of sites. Amazon always did, but the rule (from what I recall) was that if a website was based in the US (or at least had an office of some kind), sales tax had to be charged. There are a lot of places that aren't in the US, that sell US keys for games (Greenmangaming, GOG, Fanatical, Voidu, etc.). Even ebay and Steam (if I recall) didn't charge it at first. But as new laws got passed in various states, more online sites began charging sales tax. Ebay started charging sales tax a few years ago (on used items no less... that's like charging sales tax at a garage sale), along with Humble Bundle. Now there are some sites like Fanatical and GOG that have started charging sales tax as well, despite not having any kind of basing in the US (at least, I don't believe they do).
As I said, it's not much of a issue with cheap games, but when the games start costing $19.99 or more, that sales tax gets more noticeable... especially on games that are $49.99 and up.
Edit: Cleared up a spot or two.
