You can call customer service at 1-800-800-8517, Monday-Friday, 8 a.m. to 5 p.m., EST. I don't see it offered here. It is made by two companies, DMC and Zweigart. I asked others and over 90% favored the Zweigart. I looked for the size I needed and then Just googled the name of fabric (Aida or Linen), the fabric count and the word pre-gridded. Came back right away with lots of suggestions. Shopped around, found the sizes I need and bought some. Price seemed fair and I was able to pay the shipping.
I am not an employee of ECS. I am a stitcher in this chat group who saw your question.

Hello,

I’m sorry but we do not offer gridded fabric :(
