Illustrators, please learn why a page layout program is beneficial.
For example, InDesign. If you make (for example) a box layout in Illustrator with the the same product logos in multiple locations, each time you copy that logo it increases the file size, because you are copying vectors.
If you make the same box layout using InDesign, you will import the logo file to a frame. The frame is a place holder for the content. When you want multiples of the same logo, you can copy the frame. Since the frame only references the logo artwork, the frame is more efficient than the Illustrator method, since the amount of bytes for defining a four-point vector frame is WAAAAAAY less than the amount of bytes in an artwork file.
Also, since you didn't copy artwork with this method, any changes in the logo will follow through to each instance in the layout (Saving changes to the same filename as the original ensures that you don't have to re-link). A 544MB AI file can become as small as a 6MB INDD file by following this method. If you were sending this file, wouldn't you want the smaller one?
In conclusion, work smarter, not harder.
