Best buy in their ad has FFXIII-3 for $60 (MSRP) and the limited edition guide for $40 (MSRP) and are giving a free $25 gift card if you purchase both together.
I went to the register with both items. I gave the cashier the guide first and asked for a PM to Amazon for $24.68. After that, I gave him the game and my RZ (I have GCU); game came up for $47.99. Total was $72.67 + tax and I got a free $24.68 GC instead of $25 for some reason but still good for me. Way I see it, it is basically like getting the guide for free.
