Costco member savings on a new AT&T line come as a monthly credit for a fixed term. In this scenario, the benefit is a monthly credit of $2.78 that lasts for 36 months. That means you’ll see a $2.78 reduction on each bill for three years, totaling about $100 in savings over the term (2.78 × 36 ≈ 100.08).

Choosing the option with $2.78 per month for 36 months aligns with the described Costco member offer, giving a steady, multi-year discount rather than a one-time or shorter-term change. The other choices would either change the monthly amount or the duration, which doesn’t match this specific benefit.
