This website is Canadian and is clearing out their Aurifil thread at great prices. They also take PayPal. You can buy individual spools or they have different grab bags with assorted spools.

I love the 50wt. for piecing, and I've used the 40 wt. variegated for quilting. It's great thread and my machine loves it. I was using Connecting Threads and was having lots of tension and stitch problems. Once I switched to Aurifil, all the problems disappeared.
