From Twitter, for anybody on my timeline (or on your timelines!) who have expensive prescriptions:

'I was a huge fan of GoodRx for 10+yrs until I heard about costplusdrugs it's the pharmaceutical company mcuban owns. I looked up my 2 meds on the site and they were 1/3 of GoodRx price! It is mail order and I received in 3 days! Now I'm trying to spread the word to everyone!'
