I use Thousands of Bolts , They carry top name manufactures and one of the least expensive sources.

fabricdepot.com and today'squilting.com both have good quality batiks, and often have them on sale. Quality batiks are always $10/yard full price, so if you find them for $6 or $7, consider that a deal.

Be careful when purchasing "cheap" batiks; you get what you pay for. I had the misfortune of buying some from JoAnns that shrank, bled, and looked awful after washing. I have found that Hoffman and Kauffman are the best and can be purchased at many websites. Examples are Todaysquilting.com and Fabric.com. I've also found that if it does not look the same on both sides (meaning you can't tell the right from wrong side) it isn't a good quality.

Piecework Fabrics is having a sale right now and they have a large selection of batiks at $5.95 a yard.

Fantastic find. Better than Hancocks of Paducah. Thanks so much!

Currently FabricDepot.com is having a sale on beautiful batiks at about $5.50 per yard. Hoffman etc.

Normally $9.99 at my LQS.

Also, try the FatQuarterShop.com

BatiksEtc.com in VA sometimes runs sales. Awesome quilt shop if you're in the Wytheville area... Road trip? :)
I've bought her jelly rolls that she makes up and they are soooo nice. She only carries exc. quality.

I've found the best prices at

Thousandsofbolts.com and Connectingthreads.com

I would check out FabShopHop.com and search via their search engine. It will bring up shops that have batiks, the prices and so on. Also, check out some of the shops in the shop hop who usually have sales in connection with the shop hop. I have seen some beautiful batiks the shops listed by jaciqltznok, and also at Fabric Buffet. Good hunting!

I HIGHLY recommend Stitch-n-Frame.net They have Thursday
specials and frequently have batiks on sale.
I noticed in an e-mail from Webfabrics.net that they are having a sale of the great 1895 line of Hoffman batiks. However, a sale
on Hoffmans which are often $10 or even $10.50/yd is $7 which
still adds up rapidly. The sale is only until 2/12/11.
There are other web sites, like Batiks Plus, and you can look at
their sale/clearance sections but if you want to get started and not wait for sales, I'd take a look at the first two.

fabric.com is having a sale right now. beautiful fabrics.
