This "argument" has been going on for years, the usual consensus being that unless your the retailer, & probably the first to handle the item from the manufacturer or their approved agent, then the item is secondhand, irrespective if whether it's had a BB through it, & as secondhand the price should reflect that.
In fact it's even more relevant on the item we've been discussing, what if it's a lemon straight outta the box, only the first owner, who's now selling it on, has any warranty claim against this, the next owner can go whistle.
The post about the default setting for items being "used" is very valid, DO IT NOW.
