PS: The two marked YMMV are not supposed to work, but last time I checked (a week ago) they did. Everything else is guaranteed to be working as of today. On top of all that, you also get EXP for your account, giving you more % in Blue Coins from referral sales and access to better tiered deals.
PPS: If anyone wants to use my referral link that would be greatly appreciated. Just let me know through PM
