I haven't bought LEGO sets for a while, as my kids are just getting old enough to make the sets, but I am assembling the LOTR sets which I find impossible to resist.
I bought Gandalf Arrives (9469) and Shelob Attacks (9470) from Toys R Us at what seemed like an awful mark-up for them, but I noticed that I got quite a few extra pieces. Then I bought another The Orc Forge (9476) from Walmart and got marginally more than I paid for.
If this is idle speculation, I'll delete the post, but if there's something to it I'd like to know!

Even if not true (and it doesn't seem to matter which retailer we buy from), it's a great question. "Might I get more pieces at a certain retailer?" Especially since your question solicited @mcqwerty to share the "extra brick inventory" link and @Ambo100 to get Consumer Services information.
