Before you ask your Amazon Alexa or Google Assistant, you need to register on the Send me a Sample website, if you haven't already.
For full details on how to claim this, just click our button below to head over to their page but hurry as these usually run out very quickly.
If the page says the samples are out of stock just come back every 45 minutes or so to check again as they are staggering the release of freebies.
