A Rent a Classic membership makes more sense than you might think:
Rental rates are at least 30% cheaper, the membership also acts as a credit balance.
Furthermore you can collect and return your Rent a Classic at anytime, not only during business hours and last but not least, no deposit is required!
You need a membership, there is no doubt about that!
By the way: The membership is valid for 12 months from date of purchase and is NOT automatically renewed - So you do not need to worry a dismissal.
