Sam's Club Members: Spotify $120 Value Subscription - 2 x 6 months - $90
This gets you 2 gift cards for 6 months each. This is almost $10 cheaper than the Costco offer back in November, 2018.
Note: Does not work with extending Spotify w/Hulu (which I believe is not available for new subscriptions). Not sure about family plans but I doubt it will work for those either.
