Discounts based on quantity

You can have as many instances as you want in your personal cabinet, and the more instances you connect, the more favorable the price becomes for each individual instance. The "system" of discounts is as follows:

1-10 instances $11 /per instance;
11-20 instances $9 /per instance;
21-49 instances $6 /per instance;
50-99 instances $3.6 /per instance;
100-499 instances $3 /per instance;
500+ instances $2.4 /per instance.
