I should be kept away from Book Sales with barbed wire if necessary.
I went to the University Of Hawaii Press book sale , held yearly in the University gym, with a firm resolve not to spend more than $100.
I bought so much they let me back my car up to the loading dock (no kidding) to get my $$$$-worth of books which were delivered to me on a huge wheeled dolly.
I scored several about-to-be-out-of-print books and multiple copies of some wonderful ethnocultural books!
That took care of me, several birthdays and a few Christmas gifts.
As I said : barbed wire!
wow
