Weird pricing in BRL

I have D3 and both of its expansions, and no previous D2 purchases on my account.
So, if I were to purchase D2:R, it’d cost me 179.90 BRL. However, if I were to purchase the full Prime Evil pack, it’d cost 279.90 BRL (i.e., 100 BRL for D3 and its two expansions).

However, if I were to just upgrade my account to Prime Evil, it costs me 250 BRL, which is (way) more than just purchasing the standard D2:R version.

Did I miss something or there’s basically no advantage on getting the upgrade pack? Or are you telling me you’re selling two cosmetics for slightly more you are selling Overwatch for?
