Yes I think it might be a problem for some sellers that offer free shipping and then try and game the system by under sizing items when it has to go interstate or across the country and they figure that they are losing money. My post office both weighs and then measures everything sent... some people don't understand that cubic size can bump the parcel into the next weight category.

Sometimes I get customers that demand lower shipping when the cubic weight is infact increased. They get blocked usually.

I was wondering how long AP was going to let it go for.. I guess they just upped the parcel rates too in September..
