Voyages-SNCF in the United Kingdom has a big sale tomorrow. They offer GBP50 off all train tickets. Please check uk.voyages-sncf.com/en/deals/flas h-sales-promo-codes for details.
Note that the offer does not apply to rail passes. The number of promo codes is limited, and the sale is only available from 9AM GMT on August 23, for 24 hours at the most. Even though this is a UK site, it should be possible for everyone to purchase tickets if there's a print at home option available.
