Unfortunately we don't have a program for unemployed senior veterans like you mentioned. We do have a way for you to get a discounted new edition of print books you own though. If you register your print version of Programming Perl vol. 3 you can take advantage of the 40% upgrade discount for print books and a 50% upgrade discount for ebooks on the new edition. Details on how to register your book and received this discount can be found here: https://members.oreilly.com/account/b.... Hope that helps and have a great day!
