In a word. Yes!
If you are purchasing RapidScan tickets, there is no problem as each ticket has an individual barcode and can be given to each of your friends.
Some events use COBO (collection of box office) whereby you need to show your card to collect your tickets. We do advise against making a purchase using your bank card for somebody else. This is because this method of delivery requires you to present the bank card used for purchase on the door. However, we do understand that you may want to surprise your friend but won't be attending the event yourself.
While going through the checkout for purchasing the event tickets, make sure to use your name. Once you've done this you can head to skiddle.com/orders and update the name\transfer ownership of the order. You'll need your friend's name & email address.
Where the tickets are posted, and you want them delivered directly to your friend's house, you will need to follow the above instruction as well as providing their full address.
