I think we're up to $38 now. Last Spook was $65 total. They're probably spending more money overall though since more people must be getting these codes due to the longer active times.
I remember when the $5 codes were the smallest ones. I guess the $1 codes will make people excited once the codes start being .25 in a couple of years.
It's very nice that almost all of the Spook 2018 codes have been available for 30 minutes, but SS posting on social media that a code will last 30 minutes and then having it expire early really, really sucks!
(I've snagged all of the expired-early codes, btw, I just feel bad for people who missed them!)
