I am just wondering if anyone has had a problem with the new 13 oz. law? How much does one normal harlequin blaze book weigh? I have a food scale but for the life of me cant find it. I typically go into the post office if i have more then 2 books..just so i dont use up our normal stamp supply but if i have just one book and it is small ( like the harlequins) i just drop them in a mail box.

Has anyone had a problem with this?

One single Harlequin (around 250 pages) is approximately 6 or 7 oz.  Definitely NOT anywhere near the 13 oz rule.

In fact, for one single book, it's cheaper to send it First Class than Media Mail.  Find that food scale or buy another one!  It's worth it for the postage savings on single books.

How much is it for a single book (for first class)?

A 6 oz book is $1.65.  A 7 oz book is $1.81.  First class. 

But a lot of other books are only a few cents more.  I now ask when I go to the post office because a lot of books will ship first class for only $2.15, vs media mail at $2.13.  It's worth the extra two cents.

Here's the link to the USPS postage rate calculator:

My post office will automatically check to see which way is cheaper.I think they just want to keep me happy.

If you look the book up on Amazon and scroll down a bit,  you'll see all the specs including dimnsions and weight. I do this when I think a book will go cheaper (or similarly priced) for first class. I add a tiny amount for the wrapping and then go to USPS to calculate the true postage.
