There is no Halloween store. Do you mean how do you get costumes for Spooky Day/Halloween? On the first night of Spooky Day, you click on your sim and there will be an option that says something to the effect of "put on costume." You click that and then you pick what costume you want your sim to wear.
I believe it's only for teens and children as they're the only ones who can go trick or treating, but if you want the other ages to wear a costume, just click on the dresser and choose "plan outfit" then click the (+) button under everyday wear and make an outfit that looks like a costume.
Also young adults and adults CAN wear costumes if they throw a costume party during the fall. I'm not sure about elders. They will automatically change into a random costume when they attend a costume party.
To get candy from trick-or-treating you need to send your children and teens out to trick-or-treat. They will automatically go house to house.
On the three nights of Spooky Day you can have your teens and children go trick or treating by clicking on a house (that someone lives in) and choosing "go trick or treating" or "go trick or treating with..." (if you choose the with option, you can have the parents accompany them if you'd like; I'd recommend it for children).
Also, it's best to choose a house in an area where a lot of sims live close to each other. That way your sims will automatically go from house to house. If you pick a house that doesn't have any other occupied houses close to it, then you'll have to manually click on any other houses you want to go to.

Angle explained trick-or-treating way better than I did. ^^'
