no. im being sincere. how do they get the guitar strings?
do you put them up your bums?
commissary. you can 'big ticket' stuff as well as food. acoustic and electric guitars (you need headphones and a headphone amp for that though), type writers, keyboards (again with the headphones) ect... and buy all the crap that goes along with it. ink cart for type writers, keyboard and guitar case (hard or soft), strings, ect... TV's obviously, so long as you're not in federal prison.
county jail only has decaf usually.. risk of having some drug addict detoxing form booze or benzo's, then drinking coffee and having a seizure is greater than in prison.
