Example Input: I orderd this magazine in August... There should be some type of notation telling customers that it takes up to two months or more befoee the first issue will arrive.......What a waste of time. I could have gone to the library and received this magazine for free to read......I am still wating..... and there is no tracking number, therefore you just don't have a clear date for the arrival of the magazine.......not happy right now,,,,,,
Example Output: Negative
