Staples Needs a Calculator for Savings

I snapped this humorous pricing issue at Staples. Not often that the store undersells the savings on something!  The savings is either really 31.45 or the purchased seperately price is incorrect.

I am posting this guiltily since I lamented the overposting of camera phone pricing errors on consumerist of late, but I found this one humorous.  A feeling I am sure all the other posters had regarding theirs.
