Monkey asked me to post this:
If you are a Swagbucks member there is an offer on the frontpage or TrialPay dashboard for 3 months of Spotify Premium for 99 cents but you get 300SB back so that makes it free. The 300SB equals $3.
The 99 cents is a great deal but if you do Swagbucks it's an even better deal.
You will need to cancel before your 3 months is up or on the 4th month you will be charge full price. It's super easy to cancel. I've done this offer a few times now.
