"Quality brooms at low, low prices" (DP4)
If a broomstick has "splinters" (tiny pieces coming off a tree or piece of wood) and also "kreeks" while flying (making strange noises), it is not likely to be a very high quality item in good condition!
Although the date printed on the fourth Daily Prophet Newsletter (DP4) is 1 October 1999, the timeframe for that event is 1992-1993.
