There is a flat rate of $2.25 shipping added to each order for shipping within the U.S.A. and overseas for orders under 1 ounce of weight. This rate is subject to change in accordance with USPS shipping rates, and will be the cost of shipping 1 ounce of weight which has been rounded up to the nearest quarter dollar.
If you're not happy with your order, just let me know. I will happily work with you to make your order right and to make sure that you are enjoying your stitch markers. If, for whatever reason, you need to return them, there will be a 10% restock fee.
