I saw this, and took advantage of it. Of course, I ignored the minimum and spent $140 or so.
I have ordered from them in the past, and have noticed sometimes I get fabrics that are 'end of bolts,' meaning there is some masking tape where it's connected to the bolt when wound. They just go ahead and send the difference if it's 5 " or so.
Also, one time I ordered some plain colored fleece, and sent pure white. I called and let them knoiw of the error and they said they would cover the shipping to have it sent back, and replace it, shipping free, but I told ythme not to bother, it was just for dog blankets, and the dogs didn't care what color it was. I just wanted to let them know for inventory purposes. It was about 30 yards or so
