Question I Have Never Seen Before?

I've seen that Kinkos/Fed-Ex offer to pack things?? Finding boxes to accomidate the individual speakers might be a start.Then a thin sheet of foam wrap,with cardboard to surround.Bubble wrap and the outside box.
Just a thought

i have always had boxes, these are not small and are heavy, boy , got my self into one this time...probably should not have sold them except locally , but no sale last thirty days...thanks ,,,that is the answer i was looking for, just some back up on my thinking...bubble wrap seems to be the wonder drug here, i think....

U-haul has heavier grade cartons for TVs and other electronics. Not much more than the cheap crap they sell at Kinkos. I would use rigid or semi rigid foam to line the boxes, top, bottom and sides, then a double wrap of bubble wrap around the speakers, with extra on top and bottom. They should be packed to survive a 6' drop onto concrete! really!!!

UPS store can pack and ship, it will cost a bit more but it wont be denied because of poor packing if its damaged in shipping.
