You were wondering aloud how to temporarily conceal your new purchases..
One of the old timers here had sage advice; If I may quote his(or her) old post here:
"..every married man knows that the gear must be stored out of sight in cryptically marked non-translucent containers (like old cardboard boxes to attract the least attention from the better half). Out of sight; out of mind. I find discretion is the better part of valor.
Gear only is spotted when it's time to take it out, to pack for a trek, from where it has been surreptitiously sequestered away anxiously awaiting its next use. Then, you only have to deal with comments like, "Is that a new headlamp?" To which one can honestly reply, "No. I've had it for quite a while and just started using it."
Good advice which I also used in a past life.
