Wait to see how crap the blades are or are not.
I imagine the saw blades will be good. The table saw is of Germen manufacture right. So should be of good quality.
Well, they don't cost nuttin'!
I think the supplier was being fair and reasonable. Lets hope the blades are good. Have you any idea of the blades fittings? You may need to use the person again one day, or find a alternative supplier.
