I have a nifty, new paper shredder, and paper older than 7 years is disappearing into it.
In the process I ran into a bunch of receipts from a long time ago.
One June 24, 1995, at the Barnes & Noble in Auburn, MA (store #1906), I bought Programming perl. The price was $29.95.
On June 28, 1995 at the Borders at 2130 Nesconset Highway (near Stony Brook, Lon Gisland), I bought Learning Perl. The price was $24.95.
