You can submit as many or as few images as you like. However, we have a $30 minimum spend per order. Even with a subscription, if your order comes out to less than $30, you can submit your job, but our system does require payment of at least $30.
To avoid the $30 Minimum Order fee, just submit a minimum of 77 images (which is equal to $30).
