Price Matched at Target
I spent a good bit of time looking for a 3rd gen at Best Buy online yesterday when I got wind of the discounted prices. As has been mentioned, I couldn't find a single model available at anystore anywhere (even called the Clearance Customer Service to confirm: in-store pick up only, and the customer was responsible for finding one in stock).
However, I did find a very small selection of 3rd gens with limited availability at some Target stores, including the one closest to my house. I was able to get the 32GB wi-fi only in white (they had a couple left in black as well), price matched with the Best Buy print-out from the web site down to $384.99 (Target had it listed at $449.99), plus 5% off for using a Target RedCard. I think that's even a little better deal than Target was offering back in early Feb (although they marked their 16GB models down to $299 then, but, again, it was impossible to find one in stock, and it had to be picked up in-store/no online orders as well).
So there's another opportunity if you can find one in stock and have it priced matched; there aren't many 3's left anywhere these days. I also have a 4, which I agree is noticably faster on both wi-fi and in pure processing (especially with Maps), but the 3 is still beautiful and fast compared to the 2, and perfect for kids or spouses that aren't as picky to have the latest/greatest. At these prices, it's a steal of a deal. Happy hunting!
