Best Deal on 30-A Bike Rental?

My husband and I will be at Seaside (without the kids and without a car) from May 21-25. We are planning to rent bikes for our entire stay, and would love to know where to get the best deal. We (obviously) will need delivery too! Please email me if you have a recommendation gilbertphillips@comcast.net

Thank you! and Cannot wait to come back "home" to 30-A!
