We have originally purchased these for our summer vacation in London, unfortunately, we found out The Shard was closed for maintenence and remained closed throughout our entire stay, and now we´re stuck with four gift vouchers we won´t be able to use as we´re not planning on visiting UK anytime soon (we´re from Czecha). So instead of letting them go to waste, we figured out it would be the best idea to sell them for reduced price to someone who´s planning on visiting London. The vouchers require redeeming through the link in the document. (printed vouchers will be sent to the buyer) It expires in the end of 2024 and can be redeemed anytime. A purchase would be a great help for us!
