Apple products are price-locked. No second hand retailer marks up on them, like Bose. Retailers are told what to sell at and they comply or they lose rights to sell the product. If these are overpriced, it is Apples doing.
You might want to look at Best Buy's pricing again.
All iPads, iPods and Macs are sold $.99 (at minimum) above Apple.
Time Capsule 1TB $334.99 at Best Buy, $299.00 at Apple
2TB $499.99, $499.00 at Apple
Airport Extreme - $189.99 at Best Buy $179.00 at Apple
Express, $109.99 at Best Buy, $99.00 at Apple
The small accessories are just as bad. And Apple isn't the only brand they mark over MSRP too. I wouldn't be surprised is Bose products were too.
