i just posted this comment under another topic, too, in response to the same question:
i don't consider a price a bargain unless it's $4 or less per yard including shipping. here's where i start when i'm looking for new fabs online. not only are their prices great, the service is faaaaaaabulous, they ship internationally, and they can fit 28 yards of fabric into the $10 flat rate box. (not including flanel or fleece, of course):

$5 or $6 per yard including shipping is my new "normal". (took me a looooooong time to get over paying that much.) here is my second stop online. they usually have plenty for $5 or less, but i don't usually have to pay more than $6. they also ship internationally.:

i mention the internation shipping because i know our overseas friends pay so much more than we do for fabrics. even after shipping, these two sites are money savers. it depends on whether or not you live in a country that sticks it to you on customs charges.
