Dunkin' Donuts Mocha Iced Coffee 12-Pack, 13.7 Fl Oz

A decent option if you regularly buy ready-to-drink coffee, though the per-unit cost remains relatively high compared to making coffee at home or buying from convenience stores.

• Bulk purchase (12-pack) provides modest convenience and slight per-unit savings vs. individual bottles
• Dunkin' is an established, reputable brand with consistent quality
• Price works out to approximately $1.51 per bottle, which is reasonable for ready-to-drink premium coffee
