The C-store may be convienient...but the AAFES (military exchanges...stores) supply system is strange...over the years I have seen outdated stuff with high prices...and usually not what you need.
However the cadinks of today have something we old farts didn't...the internet. Amazon and others are very good at shipping what you want and quickly.
And for the record, I threw out my inkjet the last time it failed me, and replaced it with a color laser printer and a B&W laser printer, that together cost about what the ink jet did originally.
...however don't the cadets have access to networked printers?
