3 in 1 fly swatter:  $1.25 @ Dollarama

Set of 6 food sealing clips
Double sided tape

$2 each @ Yokoyaya

That's the neatest fly swatter I've ever seen!  It comes with a pan attached and even has flyers in the handle.  It was super cheap too!

I thought the food sealing clips were cute and useful.  There are even sliders so you can set a date!  I did see online that they used to sell 8 for the same price not even a year ago though.
