Yes, your subscription is flexible to suit your needs.
The frequency at which you receive your deliveries is linked to your delivery size. So, the smaller the delivery size, the more frequent your deliveries will be. Likewise, the larger your delivery size, the more time there is between deliveries.
To change your delivery size, go to the Subscription section of your account and select Change Delivery Size in the Delivery Size panel. Choose the size and select Save Order Size.
