As promised a week ago, Apple just increased prices across a range of product lines. While rising RAM costs are to blame, according to Apple, Wall Street isn’t too impressed with the move.

Apple’s stock is trading down 5% today, a 15.49-point drop, after increasing prices on existing Macs, iPads, and other products.

Apple first signaled that it planned to raise prices on its products last week when Apple CEO Tim Cook delivered the news to the Wall Street Journal in an interview.

Cook, who is leaving the CEO position but staying at Apple as executive chairman of the board in September, didn’t specify which products would see prices increases or when.

But today, Apple took down its online store, a move usually reserved for new product releases, only to bring it back with increased prices across several product lines.
