After you purchase a resource plan, the related fees are automatically offset.

For example, you purchased a Standard locally redundant storage (LRS) plan of 100 GB by using an Alibaba Cloud account and created a Standard bucket within this account. 80 GB of Standard LRS objects are stored in the bucket.

In this case, you can use the Standard LRS plan of 100 GB to automatically offset the storage capacity fees for the 80 GB Standard LRS objects.
