You mean you were getting more than $130 per $20 before?

85% discount is actually a bit lower than I remember. I think it used to be closer to 90-95%. They're getting stingy ;)

I think it was around $400-$500 last year ($20 a day was fairly common) before they added the 7 day limits (and have since slashed the 4 hour limits).

No parallel running; I would very consistently get tokens for over 3 hours then take a walk around the block and come back and be ready to go again.
