[Costco] Adults blue masks $9.79/50cts ($5 off) (Gloucester – Ottawa, Elgin Mills and maybe other places)

Costco has the masks on sale for $9.79 at its Gloucester location, not sure if 79¢ sales are location specific or not.

They still had a lot in stock.

They brought new black masks, so I assume they’re clearing out the blue ones.

Edit: 1st reaction is “-1” for “poor merchant reputation”, ok, please tell me which merchant is better than Costco?
