The following expression should capture the `{dp|gp}/$ID` part:

```plaintext
https://www\.amazon\.com/([gd]p/[A-z0-9]{10})
```

A quick explanation:
 - the `\.` are there to match periods only (otherwise it would match any symbol), 
 - `[gd]p` matches either `gp` or `dp`,
 - `[A-z0-9]{10}` matches exactly 10 alphanumeric characters
 - The parentheses around these last two components *captures* them. This is not really necessary, but the matching algorithm will be able to export only this part of the string as well.
