$5 a year for 27GB Gmail storage

When I used up my 7GB free Gmail storage, I was prompted to

• Delete some mails, or
• Purchase more storage

At first, not knowing how much it would cost me, I deleted mails, created new accounts, and set up filters, etc to free up spaces.

I soon found out that $5 per year bought me another 20 GB mail storage for a total of 27GB.
