i live in the Continental United States so i know i'm fortunate when it comes to this issue.
i look for sources that charge prices i consider acceptable. i shop the sales and/or vendors whose regular prices are reasonable. i refuse to pay high prices. period.
taxes and customs fees are a big problem for our international friends. if you know of shops that others might be able to afford, please let us know. provide information about starting price per yard and final cost after all costs have been added. don't forget to tell us where you live. (no addresses. just country and region or city if it makes a difference.)
i'll volunteer to start, post, and maintain a list once i've received some "nominations", so you can also send me the info by pm.
