Hi,
Fil-Tec is offering a sale on their Glide trilobal polyester embroidery/quilting thread from now until Sunday, April 6, 2014. Place any order including Glide thread and get free shipping, plus you get 10% off on the Glide thread itself.
The only caveat is that you have to order their minimum, which is $35. And the offer is good only for US customers..
Glide is the product that Karen McTavish uses. I love it. It's very pretty, works excellent on a longarm -- and it's made in the USA. Oh and it's reasonably priced. The customer service with this company is EXCELLENT. Call or email and a HUMAN will talk to you.
Their color cards are fun too. Real thread cards for $3-4. Yum!
Edit: Also, no affil.
Here's their Facebook page in case you want to see for yourself:
