Of course. You can list the person you want to collect the order in your customer account. This authorises them to pick up the order on your behalf. Find out how to add other users to your account here.
If you're still having difficulty adding another user, you can always get in touch with our B2B customer service team by phone 044 575 99 00 or by e-mail firstname.lastname@example.org. They'll do their best to alter the order so the right person can pick it up.
