As a former Store Manager I can honestly tell you that many (and I do mean many) of EB Games' policies are screwed up. Each store is driven independently by its local competitors which is good. Each store is also kept very individual as far as SOP, etc. In fact, until a few months ago, EB games did not offer a viewable SOP for employees to read. Granted a monkey could use the checkout system, but standard regulatory accounting procedures varied greatly from store to store.
And yes, it is true that each store is supposed to be 'self sufficient' in profits and expenses and therefore cannot always offer the same promotions and prices.
The sad thing is that a majority of EB Games locations (primarily those with more than 3-4 employees), lose 33% of thier inventory a quarter do to various internal theft/giving away items/incorrect transactions. So next time you check out that 10% off Used games, or 15% off whatever game guide, etc. Check the price tag first. Chances are you'll be paying for your 'discount', and Wal-mart, Target, Circut City, Best Buy, etc. up the street will have the same item for 25% less anyway. Granted EB will match the price but then once again whats the point in discounts? Why not save the trouble and just buy it from the competitor...?
A reason they can get away with this is also because oftentimes they do have the games before anyone else.
And about the EBGames Online Store... the store is great but the prices are very high on most merchandise, as are the stores, the internet prices SHOULD be cheaper as there is virtually no operating costs to sell online. Hell people, at least do free standard shipping!

But, after saying all that, EB Games is a really fun and laid back place to work, but if you do work there, please remember that if you take things from the company, you are only making it worse on your fellow gamers.

Happy gaming! ^^
