Using a RR B box What do I cross off to just send it priority mail?

I have never used that sort of box bt I do not think you should  do that to a regional box

I like to send plain brown boxes by priority if I have to

I have many 6 and 7 inch cube boxes I use for 1st class but somtimes they go over 16 ounces

i prefer to use 5 inch cube boxes

You don't....crossing things off do not change what type of box it is

As a rule the postal service does not allow you to change the intended use of special rate boxes.  Even if they are being reused a second time.

THAT was scary. Shouldn't it bother you that you do not know what makes it different?

If you don't wish to send it using reg rate postage, then use a plain box or a regular rate priority box.

I bet you can use that regional box with an express mail service if you want

I was always under the impression that priority mail boxes can be used for express mail since its sort of an upgrade

Nope, Priority boxes are for Priority only
