So a little while ago I signed up for the T2 Tea Society because I shop there on occasion and unexpectantly they sent me two samples of tea along with my membership card.
I received a sample of Gen Mai Cha Sencha and French Earl Grey. They're both loose-leaf and not in tea bags. There's probably enough for 2-3 cups in each little sachet.
Could be worth while if you're keen to sample some tea? By the way, it took about a month to deliver and by that time I forgot I even applied for the card so it was a bit of a surprise.
Tea samples (enough for a few cups) have always been free from T2 for me instore. Just ask for a sample or 4.
