The post office is currently slowing down shipping times and most items are taking extra time to be delivered. Economy media mail (snail mail)can take 10-30 days at times.
If you need your item faster, you may want to consider shipping it via Priority Mail or even first class if it weighs under 1 pound once wrapped up. Contact me before you purchase, so I can change shipping price. I do not ship Priority mail in a flat rate mailer, because the book will be damage.
I ship Priority mail by weight in a bubble mailer, inserted in a waterproof sleeve between two stiff pieces of cardboard.
I'm not responsible for shipping delays.
NOTE: Postage rated increased August 29, 2021.
