The same applies to yarn. I crochet winter scarves for homeless and needy people and I really need the yarn but I am on disability and can't pay that much for shipping. If I got two or more bundles will it be significantly less by sending it all together>
With the yarn i am finding that one bundle fills a flat rate box costing 13.00. I get as much as i can in but its cheaper to do it flat rate for yarn and fabric most of the time because weight is a factor for this. If you win yarn and book i can get the book in there with one box. It would save the cost of the 3.00 for the book.
