Apple is still attempting to resolve problems with overcharging at the iTunes Store, anecdotes indicate. Following the introduction of selective iTunes Plus upgrades last week, some shoppers have reported that after choosing to upgrade an album, they have been charged the full price rather than just the cost to remove DRM restrictions. Upgrades are set at 30 percent of an album's normal cost; most albums cost approximately $10.

Apple states that it is aware of the overcharges however, and is willing to issue refunds to people who complain through the Report a Problem buttons located in a user's Purchase History page. Refunds can take as long as five workdays to complete, but the company is known to be issuing song credits to some disgruntled customers. People who have not yet upgraded iTunes content may wish to remain patient until Apple confirms a fix for the upgrade process.
