What is the best way to pack and ship a bulky laptop bag?

Try one of those Vac Packs, you know the ones they advertise on tv.

a box would be better, you want it there in one piece especially since you sold it.

I just don’t know where I’d get a large, flat, rectangular box. These things have lifetime warranties- I’m not worried about it getting tossed around.

Take it to a UPS or FedEx store and they’ll pack it for you, or you could try the boxes they have at the post office.

Bubble wraps are great combined with styrofoam peanuts.

If it’s soft and can be dropped yes you can just wrap it well but you need packaging tape, Staples sells boxes of all sizes and tape or just go to a supermarket when they are packing out groceries and pick up a box.
