Good for a cheaper trip into town, or an escape from it into Kent. Similar
to the offers Southern have been running for some time now (though
Southeastern doesn't offer Advance fares).

Tickets have to be purchased online from their website. Discount is for
off-peak ticket types. Valid on all Southeastern services including
Highspeed, though excludes London Travelcards (both inboundary and
outboundary) and tickets for travel wholly within the London fare zones.
Railcard discounts also valid, inc. Network Railcard (so 'double discounts'
possible).

(Those heading into London would likely be better off purchasing one of
these discounted tickets, then buying a zones 1&2 Day Travelcard on
arrival - cost GBP 6.60, or GBP 5.30 with Railcard - or using Oyster PAYG,
compared to just buying an undiscounted outboundary Day Travelcard from
their origin station.)

Shame the booking engine currently displays the discounted fares with
cryptic names such as "WEB SUPOFPK D R", "WEB OFFPK DAY R" and "WEB OFF-PEAK
R" - yes, we might be able to fathom it out but it's hardly that user
friendly when they're trying to entice leisure passengers onto the railway!
One hopes this might be remedied shortly.

An aside - the English language rather lets one down here - this promo can
be described as offering a "discount on off-peak tickets" (on - off), or
"20% off off-peak tickets" (off - off)!

(To those on uk.r who are riled by mention of the metropolis, afraid this
won't be the last time so do pls do make use of your kill-file.)
