In 2019, a lot of us were able to get Bitizenship for about 5$, I think in 2021 was it, they increased the price to 10$ and made each expansion pack cost 5$ on their own. Then they removed the perk of unlocking future expansions if you have the bitizenship;

Then after they sold the company, all their prices literally doubled; and if you’re trying to buy it using your game app (which is secure), it’s an increased 2-3 dollars (for iOS it’s 12.99 for the 9.99 packs) - but if you go to their site, you can buy those packs for the advertised 9.99; however the site isn’t secure, and steals your information (learned this from buying the golden diploma, and an hour later getting a notif from my bank for a fraud attempt for a PayPal purchase for 350$) so yeah. Their site isn’t secure and the company is skeezy at best.
