Bad bindings = sad customers
I have sold several books through bookpatch.com, but my most recent experience caused me to switch to KDP Amazon. Initial production problems with bindings caused pages of my hardcover books to fall out. The company replaced a few copies and then refused to replace any from that same production lot since the complaints did not fall within the 30-day warranty window. A book should last a lifetime, not 45 days. They also locked up several offerings that had to be uploaded again.
