Unfair pricing for Legacy of the Void

I wish to file a complaint about the current purchasing structure of the Starcraft 2 expansions. I had previously purchased both Wing of Liberty and Heart of the Storm, and wish to buy the last expansion at your holiday price. But I see that you have bundled both the expansions and even at the “sale price” the cost of the expansions is the same as buying one full expansion. I noticed that there was a very small “reduction in price” for owning Heart of the Swarm of $9 which was a joke.
