Expenses

I am truly shocked at the price of fabric, I've even started to visit the charity shops for remnants now, The ladies from my local fabric shop have said every time they place their orders for more fabric the prices of cotton and silks are going up weekly. How can we make and sell our handmade products at a decent affordable price if the fabric is so dear in the first place? Anyone have any ideas on where to find fabrics that are not at high prices?
