If you manage to grab a copy of The Guardian today (80p), you will find a voucher that entitles you to a free cuppa Starbucks exclusive red cup yuletide inspired coffee, worth £3.
The voucher that states that this offer is only valid for today. But a couple of phone calls to The Guardians Press Office this morning confirmed that this was actually a misprint.
Apparently the voucher will be honoured until 18/11/2008.
