Purchase Recliner Beach Chairs In St Lucia

Last time we were renting a house, in Soufriere, we had to pay $10 per lounge chair at the "Anse Chastenet" and $20 per chair at the "Jalousie Plantation".

This time we would like to purchase chairs/lounges that we can carry to the beach, since all beaches are public.

Where can we purchase recliner Beach Chairs if we are staying in Soufriere?

Thank you for your help.
