How did you get this? Is it still available at that price?
Yeah of course. You need two things:
1) $150 Off Surface Pro 3 edu coupon (free on Best Buys website if you have an edu email address, a few bucks on eBay otherwise)
2) 10% off single item Movers Guide coupon, costs $1.05 on the USPS website. You don't have to actually forward your mail, just go through all the steps until you can print the coupon, then cancel.
Best Buy usually has a one coupon per item limit, but if you can get the cashier to scan both coupons for the Surface great. Otherwise the trick is to have them ring up the Surface plus one other cheaper item, hand them the $150 Surface Pro coupon first, then hand them the 10% coupon and tell them its for the second item. It doesn't matter what you tell them, or what they do; the 10% off automatically gets applied to the higher priced item (the Surface). If they don't pay too much attention you'll be getting the i3 Surface for $585.
Details for all of this are on Slickdeals.
