For example, you want to make several changes to several pages on your website:

• Remove one previous promotions.
• Update the contents of another previous promotions.
• Add in 2 new promotions.
• Add a photo to the profile page.
• Add the same photo and a link at the home page so that users can access to it via the home page and the profile page.

Your cost: 1 update, which is about $15.

However, do note that even if it's just 1 change (it does happen occasionally), for example, you just want to:

• Change a sentence in a page.

Your cost: same 1 update, which is about $15 but still very affordable!

From experience, it's very rare that you only need to make 1 change to your website thus you only stand to benefit in the long run!
