Starbucks VIA $1.00 Off

So I was in Starbucks today and I asked them if they took coupons. Their response was if our computer takes them we take them. So…

At Starbucks their 3 pack of VIA is $2.95. Coupons.com has a coupon out right now for $1.00 off any pack. What does that mean? $1.95 for the three pack. They make great travel packs actually.
