Just ordered from this company. They actually had to go out of their way to price shipping for me as I'm in Canada. She phoned me back and let me know. Then I had to phone them to place order because of their website not liking my PO Box. Very friendly, very helpful and a joy to talk to. Also their prices were at least $10 cheaper then anywhere else I could find them, which was only 3 places.
It was $35 for a case, which is 10,000 tachs, plus for me it was about $7 shipping, way cheaper then I even dreamed of. So well worth it. The link below will take you to the page and they are at the bottom.
However please remember I was ordering tachs for the MicroTach gun, which also fit into the Microstitch gun. As per AveryDennison the manufacturer of the gun the only difference is one is meant for industrial use and the other for home use. Also I was able to order just black, or you can order just white. When you order the little pack from others you are not able to pick color as they come in a mixed pack of black and white. What a pain it's going to be to pick out those white tachs from a white quilt. But I had no choice as I had run out of the black.
