My main reason for not ordering online is because I don't buy cotton .. if I were a quilter or used cottons for my bags, I may .. but when I inquired with a US company about shipping for 2 yds of their tapestry at $20.00 a yd (I would pay $32.00 here for similar) .. the shipping was going to be astronomical .. far more than the gas I would burn going 15 km to buy it locally .. for me, it just wouldn't balance out .. and yes, I would pay tax/duty and GST because of the weight and the cost .. in addition they used UPS which would have incurred a brokerage fee .. plus I couldn't feel the quality ... I know gals who go to their own quilt shop and see, feel the fabrics and then order it online and of course if you are ordering Moda or something like that, Moda is Moda no matter where you get it ..
