95% of my fabric purchases *outside the local quilt shop* is from fabric.com. i've been shopping with them for over 10 years- even when i made more clothes than quilts- they offer free shipping at the $35 level & i can always spend $35.
they have a huge selection and great prices- wonderful customer service...i really recommend them to everyone shopping for fabric away from their local quilt shop. i at times buy something from a couple others---but the majority of my fabrics come from them.
