Calculate the yardage in the precuts and then compare with the price of fabric by the yard. You will discover there is a "cut" charge built in.
Fabric in quilt shops is now selling for $10-$12 per yd
So probably any price less than this is a good price.
However, check the quality if much less.
There are shops that sell for less and quality is good
I posted a request for suggestions for reasonably priced fabric. Search for that posting.
Many shops still have fabric at around 7-8$ per yd.
