Blizzard have just released the Welcome Bundle in the shop which you can buy for £3.99 / €4.99 / $4.99 in the shop. The bundle contains 10 random classic packs plus a guaranteed class Legendary which may or may not be a duplicate of one you already have.
This is the cheapest, real money for cards-wise that have ever been sold. Thing is I'm saving gold like crazy for future expansions and vowed to never spend any real money on the game ever again but this seems to cheap to pass up, it's only the price of a cheap lunch ffs. Blizzard have us by the balls on this one.
Will you be buying it?
