My vouchers are available to any value and can be redeemed against any of my services, subject to availability, of course. They come without an expiry date, so can be used at any time.
All you have to do obtain a voucher is
contact me
with details of who the voucher is for (which could be yourself or someone else), how much you want the voucher to be worth, and where you want it sent. I will then send out a code-numbered voucher by post.
Then, the voucher holder can redeem the voucher against whatever service they wish by contacting me with their voucher code!
