Qobuz.com is discounting many of its 24-bit downloads by between 10% and 30% this weekend (till January 31, 2012), plus if you spend 50 Euros you get a 20 Euro voucher for future use. Their selection is getting quite large; the sale marks their 1,000th hi-rez ("Studio Masters") title.
Some of their titles have territory restrictions but as a U.S. based classical buyer I was able to purchase most of the titles I was interested in. I have no connection with qobuz.com other than as a retail customer.
