I'm definitely a thrift store/ yard sales shopper as a rule! It's amazing what you can find on the right day, at the right time! I wish I could support LQS and buy brand new, but raising a young family on one income has made me appreciate our grandmothers who quilted with what they had on hand. My MIL gives me anything she isn't using, so that has been a great help for my stash.
I don't really do fabric lines, but in the past I have splurged and bought a charm pack of fabric lines.
I watch on-line stores for sales, but generally convince myself that I can manage without when they do have a sale.... Sigh! (The joys of being tight-fisted!)
