I'm interested in becoming a member of The Poetry Book Society. Please describe the different membership types available, their annual costs, and the key benefits associated with each type, including how members receive their quarterly poetry selections.
Navigate to 'poetrybooks.co.uk'. Click on the 'Membership' link. Identify and list the different membership types offered. For each membership type, find its annual cost. For each membership type, identify and list the key benefits, specifically noting how quarterly poetry selections are delivered. Synthesize all collected information into a concise answer.
The agent successfully navigates to the 'Membership' page. The agent identifies and lists the different membership types (e.g., 'Full Membership', 'Digital Membership', 'Student Membership', 'International Membership'). The agent states the annual cost for each identified membership type. The agent details the key benefits for each membership type, including how quarterly poetry selections are received (e.g., 'four quarterly poetry parcels delivered to your door', 'digital access to the Bulletin').
