Under a pilot program detailed by officials Tuesday, residents may order 20 large city garbage bags through Amazon for $33.60, a cost of $1.68 per bag. Delivery is free.

Demetrius Tart used to collect between 17 and 18 tons of trash each day along his route in Alpharetta, Ga. Now it's more like 22 tons a day. "The cans are overfilled," Tart said.

In January, customers could order 20 large city garbage bags through Amazon for $33.60, or $1.68 per bag. Amazon's listed price this week is $46.75 for a set of 20 bags, a cost of $2.34 per bag.
