The 20% discount is every 3rd Sat of the month - it's done by the quilt shop next door. The sewing machine store does rentals for the quilt shop classes.
It's ok to wait. The prices were not bad on the machines.
2.0 - $1560
3.0 - $2080

They had Berninas too, not that impressed with those though. Didn't like how there was a blade to cut inside of the throat area on one machine.
