Fab Gift

This is a great gift for a lager lover - generous samples of a variety of Hawkstone lagers / cider and a vodka! Very interesting tour with the history of how Jeremy Clarkson came to be involved

Fantastic show

My friends bought me a theatre voucher for my 60th birthday. Although the choice of shows is limited, there were plenty that we wanted to see. The main problem was that we can only go to London on Saturdays and, as you would expect, most of the shows were sold out. The price to upgrade to extend the tickets was crazy so in the end we plumped for Wicked as it was the only show with seats available. Similarly the only seats you could buy with the voucher we had were literally the furthest possible from the stage, and again the price to upgrade was crazy. However we could still see and definitely hear everything. The show itself was incredible- the theatre front of house staff were all lovely and very welcoming and the show was phenomenal. A fantastic gift!!

Best gift for kids

I bought go ape adventure for my kids and my nephew, 15, 11 & 10 years boys. They loved it so much, it was the first time for them. It was slightly complicated booking as I had previously purchased gift card which was not used, but the buyagift team sorted out instantly. The 'go ape' team were really helpful, from the beginning till the end. I would definitely recommend them and we will definitely go back for further challenges.
