That’s a huge price increase. It was only $70 per K2 case last year. When I was in San Diego in February, I got a K2 for $75 and was told that the price had just recently gone up that $5. I once counted a case of 2x4s and it contained 624 bricks which is $0.112 per brick. At $75 per case, that would be $0.12 per brick. At $100 per case, it is $0.16 per brick. So that is basically a $0.5 increase per 2×4 brick.
However, searching for US sellers on Bricklink with at least 624 2×4 red bricks (common color) for sale, there are only two sellers and the prices are $0.27 and $0.36 per brick. Same with Blue – 2 sellers in the US, one at $0.24 and the other at $0.31. And these prices do not include the shipping costs that would go on top of the brick price. So at least for 2×4 bricks in k@ quantity, a $100 K2 case is still a much better deal (at approx. $.08-$.10 per brick) than Bricklink.
But I am still not happy at this 33% price increase. 🙁
