My local Futureshop has the model I want for $100 off. I can get it for another $130 off by purchasing a refurbished model through Apple. With tax I'm saving about $150. So is it worth saving $150 to buy refurbished through Apple? Also I hate Futureshop, just tossing that out there. EDIT: To add in case it matters I'm looking at the retina 13" with 8GB RAM and 256SSD.
