Probably late to the party, but there is a 60% sale on, so all expansions are about $23 in my country. I purchased on my main, and then the others. I then used my main account to generate their ‘Recruit a Friend’ codes for each slave account, When I do start paying the subs, as I get 30 free days as part of the collection purchase, the accounts get some booties.

I used a seperate email for each account. You can also sub on your main account, and use that account to invite your slaves to the party for dungeons if you want to make the most of the free trials, but you may miss the discount at the moment, sorry, can’t remember when it finishes, Make sure you purchase from the store and not steam, or all other purchases must be via steam in the future.
