Flap discs are pretty much so expensive that I stick to grinding wheels,,
the flap discs sure do a nice job of prepping for paint,,, though,,,
I found this offer, and ordered my 10 free flap discs,,

Be sure to enter "FREEMIX" at checkout,, the $23 price goes to $0,,,
There is a $10 shipping charge,, that is reasonable to me,,,
