Review on Partners Brand P963 Corrugated Boxes by Chad Judex

So everything in the description and even on the box says it's 9x6x3. However, if you take a ruler, it only measures 7 3/4 x 5 1/4 x 2 3/4. Very disappointing as it will delay receipt of my items as I have to wait for large boxes to arrive as my item is 5 1/2 inches wide. The most frustrating thing is that nothing can be done except return the money.
