Pricing at LCS usually depends on how good of a client you are. Have you bought from him many times before? Maybe if you start pre-ordering all your wax from him, you'll get a better deal. My LCS owner (who has also become a very good friend of mine), gives me a great deal on wax. I buy everything from him and pay well under regular retail because he knows I spend all of my hobby $$$ at his shop including supplies. I will also help him sell singles online and often sell him many of the cards from my breaks (at a discounted price) when he has clients for them. It's a win-win for us both.
The shop you frequent paid approximately $1200 for the 10-box case. At $1450, he's making just over 20% profit which is pretty close to full retail. I'd have a talk with the owner. Tell him you plan on becoming a regular case breaker and see what kind of deal he's willing to cut you. Doesn't hurt to ask
