How does this happen?

Q-tips display at The Real Canadian Superstore, Vancouver, BC

I found this empty display a few weeks ago at a branch of The Real Canadian Superstore in Vancouver. Seeing the completely empty shelf made me wonder who this sort of this could happen.

• Were sales just so overwhelming that the store ran out of stock?
• Was the display put on the rack, and then stock didn't arrive?

I don't think of the Q-tip as highly popular impulse item, so I find this sort of mass display a bit puzzling to start with.

Regardless of the reason for the empty displays, the bare rack does not speak to a high standard of visual merchandising.
