I order my aurifil from Sue's Sew EZ Designs www.sewezdesigns.com she has a sale right now for 7.00 a spool and she can ship several for 5.00. I just ordered Monday and got it Wednesday. She was recommended by someone on this board a year or so ago. Have been very pleased with her thread and the way she packages, sealed and very prompt.
Good Luck
Suzy
