commit 2545b258f234e3d5806bb25b25fcf72505937ac6 equwal <truex@equwal.com> 2026-09-22 15:55:31 -0700 Sell a 500-book pack Add pack500: 500 credits for $174.99 ($0.35 a book, 30% below the 10-book pack). The owner chose to sell it against the advice of the financial advocate: one such sale can hold the one CPU server for about six weeks. So the pack text says how fast the server works. The catalogue tests now expect three packs, and the check-out test runs for pack500 too.
