Thank You for the repy, What I found also was if you change anything on the listing it resets the boxes clear. Problem is I have a lot of products that won't fit in a small flat rate box or envelope. And I have to insure that an international purchase made with products that do not fit in a small flat rate box, doesnt show that rate available at checkout. Or i will lose alot of money on shipping. So you can't be sure that the boxes didnt become unchecked from editing or changes.
Wish there was a better way for blocking small flat rate boxes, when the products purchased won't fit.
