Just like to point out that the Production Department, and the Advertising and Printing Departments are not intertwined.
On that note last month when PotC was coming out LEGO Brand Retail had three different release dates for the sets; the date printed on the In-store Events calendars, the official country by country release date emailed to every store globally, and the date of actual product arrival; the last being the date we ended up having to go by simply because we can't shelve what we don't have in stock, meanwhile our local TRU had them a week ahead of our earliest release date.
As to quality control; my biggest personal gripe isn't with the colors it's with the quantity; I have to refer at least a dozen customers to the "missing bricks" link on the LEGO website during an average 8 hour shift.
And why the heck do the faces on my keychains only last a max of 6 months before they fade away? Poor Doby was blind after about 2 months of being on my keys.
