I get a daily email from this web-site:

Last week, it was a different Benartex charm pack or jelly roll every day for 42-46% off.
Missouri Star Quilt Company also has a daily deal that is often a jelly roll.
There are Jelly Rolls & Charms on Joann.com, also. They had a jelly roll on clearance yesterday for $3.19, I believe.
