You buy the voucher and receive the code by email immediately.
The code is the surprise. How you wrap it or share it is entirely up to you.
At checkout: enter the code, the amount is deducted. Partial redemption possible, remaining balance stays on the voucher.
Written honestly:
It depends on the person you are gifting to. The EUR 100 voucher is a nice contribution to a race taxi (GT4 starts at around EUR 149). The EUR 250 voucher covers a full passenger package or a major part of a race taxi experience. The EUR 500 voucher gets you close to a driver ticket (from around EUR 599) or makes up a substantial portion of a race taxi day.
Then you simply pay the difference by card or bank transfer. The voucher deducts the corresponding amount, you pay the rest as normal.
The remaining balance stays on your voucher code and can be used for your next booking. Vouchers are valid for three years, so you have time.
The voucher carries the purchase value you pay today. If the experience becomes more expensive, the recipient simply pays the small difference. If it becomes cheaper, the remainder stays as credit on the voucher.
