I used this site too. Remember to check the tax region. Set it to Brazil ;) £6.50ish
Bought. Thanks OP. I also added on 2 mystery games for £1.49.
Cheaper elsewhere, only by a quid and a few pennies. https://www.instant-gaming.com/en/1691-buy-key-steam-tropico-5-complete-collection/?currency=GBP&gclid=CjwKCAjwmf_4BRABEiwAGhDfSbYOWsw5fZXGXVKTqWJDqvrzc5yPYD26WVTnxLU77cjolt5N5d8H3xoClA8QAvD_BwE
It's a great game, but Im pretty sure it was in a humble bundle recently. No one has a time machine, but I'm damn sure I paid a lot less than this with lots of other games.
