From the page:

Description
The STM32F3DISCOVERY helps you to discover the STM32 F3 series Cortex-M4 mixed-signals features and to develop your applications easily. It includes everything required for beginners and experienced users to get started quickly.

Based on the STM32F303VCT6, it includes an ST-LINK/V2 embedded debug tool, accelerometer, gyroscope and e-compass ST MEMs, USB connection, LEDs and pushbuttons.

A large number of free ready-to-run application firmware examples are available on www.st.com/stm32f3discovery to support quick evaluation and development.

Key Features
    STM32F303VCT6 microcontroller featuring 256 KB Flash, 48 KB RAM in an LQFP100 package
    On-board ST-LINK/V2 with selection mode switch to use the kit as a standalone ST-LINK/V2 (with SWD connector for programming and debugging)
    Board power supply: through USB bus or from an external 3 V or 5 V supply voltage
    External application power supply: 3 V and 5 V
    L3GD20, ST MEMs motion sensor, 3-axis digital output gyroscope
    LSM303DLHC, ST MEMs system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor
    Ten LEDs:
        LD1 (red) for 3.3 V power on
        LD2 (red/green) for USB communication
        Eight user LEDS, LD3/10 (red), LD4/9 (blue), LD5/8 (orange) and LD6/7 (green)
    Two pushbuttons (user and reset)
    USB USER with Mini-B connector
    Extension header for all LQFP100 I/Os for quick connection to prototyping board and easy probing

$10.90 and then there's shipping.

Perhaps it was the...

you were thinking of?

[stridera]

Nope.  Free as in they'll send you a free kit.  I got the link from reddit and according to the comments there, it doesn't seem to be available in Europe.  (Sorry)

I was able to successfully get a free copy as were others.

I guess outside North America, the free button isn't there for you?

[Soeren]

Ahaa, OK, I tried a few anonymizers (they allow me to see the US prices on LEGO, which is about a third of prices here in DK where it's from LEGO is cheaper everywhere but DK, but without proxying, they hide that fact).
No luck on getting the "Free button" though.

Well, it's not that I am short of boards, but I'm always curious of new promising controller/processor boards

Out of curiosity, did you have to pay shipping charges?

[stridera]

I didn't pay anything.  Haven't received the board yet or anything other than the confirmation email, but I suspect it's all covered.

I got my board a few weeks ago and it came as advertised....  completely free, not even shipping charges.
