FA few days ago, my best friend told me, that she needed to buy some stamps.

This is 2022; how many of you willould go to a post office to buy a stamp and, post a card, or letter to send to your local or overseas friends?

Because she hadn’t been to a post office forin such a long time.,

Alone, this isn't a complete sentence and should be combined with the next sentence.

Sshe was surprised by the latest stamp designs and quality.

Continuation of previous sentence.
