I love the kits, fabric and thread at Connecting Threads. They don't have a ton of notions though. When sewthankful -
http://www.sewthankful.com/ - had their 1.99 flat rate shipping I purchased a few items from them and was very pleased with their products and the quick shipping. I buy quilting books on Amazon and some items on ebay. I guess if I am looking for something specific I will just search around and see who's got the best price.....
