I would have to say that I have never bought more than 2 or at the most 3 fabrics together in a line. I also do not care if it is "the latest", I shop for what I like, and what calls my name. I enjoy the process of pulling fabrics from all over to come together in my quilts to contrast and complement each other. I have to confess, I will frequently go to the back of the store upon entering to see what it at the sale tables before I search the rest of the inventory. I love to get a good price on fabrics. My LQS here down the road will often have "Designer Cuts" of fabric, that may be the end of a bolt or something they got from the distributer or something that is of same high quality that they will mark at 50% off. Usually it is in a piece that you have to buy the whole thing of, anywhere from 1/2 yard to up to 3 yards. I have purchased many of those and then gone through the store to find something to "go" with it. A favorite store, that closed back in March, used to have huge sales on holiday days and would put tons of fabric on sale for $1 or $1.69 or $3 a yard and that is where I got most of my fabrics. I have learned which fabrics to buy and which are not worth putting in my quilts.
So.... having "last years" fabrics for a cheaper price is what I would look at first.
