So, I finally found a person in US who's willing to send me new LEGO sets to Europe (just bricks and instructions to keep the shipping fee down). What's the best way to track LEGO prices in US? Amazon Warehouse, what else?
Honestly, LEGO S@H is the most reliable. That's what most stores sell for. Occasionally you find 5-10% cheaper at Walmart/Target/etc, but even Amazon has gone more towards MSRP.
