What is the fastest way to get pet slots? Buying them with SP or some other method?

(Sorry if this is in the wrong area.)

There are now Pet Slots in the Millionaire Center for 20, then 40, 60, 80, 100 mil. 20 mil is the cheapest pet slot you're gonna get. I don't know how much 2k CSC is going for these days, but I think it's somewhere in the 100 mil range, and that's the price for a regular Pet Slot.

Pet slots no longer go on sale for Black Friday either, so once you've bought all 5 of your Millionaire Center slots, they're 2k CSC each unless you wait for your loyalty box every year (you get your first one for being a member for 2 years though)

Would you say that's good value for money, then?

If you're an avid pet collector, I'd say they are.

I just realised that buying two slots now requires more sP than I have, so... Whoops, I guess.

Absolutely

How much real-life money is equivalent to 2K CSC?

$20, its $1/100 csc not counting sales and bonuses

The cheapest AND fastest way would be the pet slots from the Millionaire Center. Once you get those, you have to decide whether you want to get a pet slot the cheapest way OR the fastest way. You can't have both.

If you want to do it the fastest way - You can buy the for 2,000 CSC each.

If you want to do it the cheapest way - You can get pet slots for free with loyalty boxes, but you have to wait to get your first one 18 months from now. Then after that, you get one every year on the date you joined Subeta.
