10% Discount Online 16-25 Railcard
Instructions: Okay, so Everyone probably knows what the railcard does - it offers some quite good discounts on train fares for 1 year. If you are going to use trains on a semi-regular basis, it'S a pretty good idea to pick one up, and they are now offering a 10% discount for buying online.
Also, you get a year's free YHA membership (UK Youth Hostel Assosciation [url]http://www.yha.org.uk/[/url] usually £9.99) when you purchase online, details to be given on completion of purchase, apparently.
Some other intersting points you may not know - you can buy a new 1 year railcard up until the day before your 26th birthday, and it is vaild for the full term of the railcard, so don't worry if you are now 25 and aren't sure you'll get a years worth of train travel out of it.
You can also get a 3 year card for £65, and on the assumption that british train fares will only ever go up in price (probably a lot faster than inflation), and consequantly so will the cost of railcards, this is probably a decent idea. Unfortunately, there is no 10% discount for that - but that can be bought up until the day before your 24th birthday, and will remain valid for 3 full years.

The £20 tickets for Avenue Q looks particularly good to me.
