Dump unused goody bag toys into the Halloween candy bowl
Abbe's found a way to unload goody bag "treasures":
We always have a few random things in odd quantities leftover after our daughter's birthday party - the bouncy balls came in packs of 24, the markers were in a 16-pack, we thought we might have 9 kids but only 6 came, we entirely forgot to give out the goodie bags except to one or two kids we saw the next day, etc. Last year, I happened upon the leftover goodie bag stuff while putting the candy into a bowl for trick or treaters - so I just dumped all the markers and bouncy balls and stickers in with the candy. Kids actually chose this stuff preferentially over the Reeses'!
This hack helps more if your child's birthday party is coming up in the next few weeks, or you are a very well-prepared packrat who saves this kind of stuff *and* can still find it at the right time.
