I thought it would be useful to have an overview on what's discounted in the PAL Wii U eShop right now. Did i miss _{or screw up} anything? (Please include your source since i don't have a Wii U yet so sadly i can't look it up in the eShop.)

current discounts
Trine 2: Director's Cut - €12.49 (was €16.99) / £9.99 (was £13.99)), discounted until 7th March _probably
F-Zero - €0.30 (will be €7.99?) / £0.30 (will be £5.39), discounted until 21st March
Wii Street U - free

permanent discounts
Little Inferno - €9.99 / £8.99

previous discounts
Mighty Switch Force: Hyper Drive Edition - €4.99 (was €9.99) / £4.49 (was £8.99), discounted until 28th February
Tank! Tank! Tank! - My Kong Mode - €1.99 (will be €9.99) / £1.59 (will be £7.99), discounted until 28th February

F-Zero will be £5.39, and Little Inferno is actually £8.99

I can't find a source for either, other than I'm on the eShop right now.

Updated. Thanks Olimar.
If you look it up in the eShop there's no other source needed of course.

i've just paid € 10 for Mighty Switch Force: Hyper Drive Edition + Tank! Tank! Tank! - My Kong Mode + my first Zen Pinball 2 table... nice!

Sorry it took me so long.
These should be the current discounts in the Wii U eShop.
As said before, feel free to tell me if i got something wrong, forgot anything or something.
