Does BRICKSEEK work for ANYONE?!? I've never had store prices match what Brickseek says the price will be. I get that their service says it won't always be in sync with what a store carries QTY-wise, and that prices can vary, but i've NEVER had success with Brickseek. I've tried Walmart, BestBuy, Lowes... no luck anywhere. Am I jinxed or is this common?
