Unlimited group plan for 4 people with Spotify premium (one free and three 50% off) for $40 each as response to 2degrees campaign.
Officially it's $29.99 a sharer, but can ask rep fo $10 discount as competitive response.
Great to combine other deals as the Samsung Galaxy S10/S10+ (buy one and get one S10 free, when sign up for 2 years) or the Huawei P30 deal with smartwatch and wireless earbuds)
