Do you weigh your books when using printable postage or just go by what the system gives you?  The first few books I shipped out I took the time to run to the post office and all but 1 were exactly right.  The one that was off was only 3 cents over what was required.  I've since mailed out books using printable postage and have gone by what is in the system.  Would it be feasible to invest in a scale or have you found the weight in the system to be accurate?

Thanks!

Hi Jaimie!  Definitely invest in a scale if you can :)  Sometimes (actually, most of the time) the PBS weights can be WAY off!  I bought my scale from eBay...and I would be lost without it.

I weigh them. Sometimes they are way off like Susan says.  Usually I find that the weight on PBS is higher than the book. So getting a cheap scale will pay for itself.  Also if it's under then the book could arrive postage due or be sent back postage due. 

I got a small scale at Walmart for around $10. 

I weigh them. A lot of the hardcovers I get are book club editions which weigh a lot less than the retail books, although they share the same ISBN. The system will sometimes say a book weighs over 2 lbs when the one I'm sending is actually under 1 lb. I have a cheap food scale that I got at Target and it works fine for weighing books too.

I weigh my packages. No sense in over- or under-paying the postage. :-)

I've gotten burned by the wrong weight problem.  I then bought a scale to prevent that from happening again since I can't just op out to go to the post office.  I depend on printing out the labels and postage.
