It really depends if amazon has any sales on classic monster or horror movies. I love watching them throughout the year, but especially in October. I don’t do much for Halloween itself, I’m usually working and don’t really enjoying dressing up.
In our neighborhood, if your exterior lights are not turned on, no one comes to your door. Since I keep mine off that night, I might be saving money.
$10.56. That’s ten bucks worth of candy from the dollar store plus tax.
Most years we don’t get many kids and I have way more than enough. When that happens whatever kid comes to the nearest to when trix or treats is supposed to end get’s all the remaining candy dumped in his bag. I love to watch their face when I d:eek: that. One time this boy about 11 said to me “Dude, you rock!” Made my day.
$10 on pumpkins
$20 on candy
$20 on costumes for the dogs.
We sit on the front porch with the dogs and hand out candy. It’s usually the last night of the year we’ll be out there before it gets too cold (and some years, it’s gotten too cold). But it’s a good chance to talk with the neighbors and the “not neighbors” who drive to our area just to trick r treat.
I buy 3 or 4 bags of candy–around $10. That’s enough for whatever kids might come to the door, and enough left over for me and to take some to work.
Between kid’s costume and candy, maybe $25.
Oh, but I forgot about pumpkins. We usually get three large jack-o-lantern pumpkins, but get an assortment of slightly smaller pumpkins, gourds, and squash at a nearby patch. Typically spend $20 - $30 on pumpkins too.
Candy, about $30. Non-candy treats, about $40 (We do the teal pumpkin thing)
Pumpkins, about $15. Two for the front stoop stairs, one for the wildlife
We have outdoors decorations, but I spent maybe $50 on the whole set up - pathway lights, lighted handrails, some of those fake tombstones, and a few light up plastic circa 1970 ghosts. The door gets decorated with “cobwebs”, lights, and a large skull wreath. The door was about $30.
Indoors, though… My daughter has a huge Halloweentown set up. I can easily say we’ve spent over $500 on that. Plus we light the windows, I have a tableau in the living room, we have Halloween themed towels, soap dispensers, shower curtain, candle holders, and our cat even has Halloween themed bowls.
We love Halloween around here.
Just enough for candy that we can either give to kids who come by or eat ourselves. Max is just a handful of visitors, so there’s always candy leftover.
We buy a lot more candy when it goes on sale afterwards.
A costume for the kid, a big pumpkin to carve, and one bag of candy for us to eat while trick-or-treaters don’t come by–about $50 all told.
$50 on the younger kid’s costume. Another $20-$30 on candy. We used to decorate more but we’re busy and tired these days, plus the neighbors put on a HUGE display so who cares about my plastic skeleton and cloth spider?
Last year was our first Halloween in our house. Neighbors said to expect 200 to 250 kids, so we bought for this many. Ended up with over 400. We started rationing after half and hour and the last few bunches got some things like granola bars from our pantry. We shut off the lights at 8 when I went to bed. A few older kids still knocked, my wife gave them pencils.
For the last 12 years - nothing. Before that, it varied according to whether my husband and I were going to a costume event or if our daughter wanted something specific for a costume. Few places we lived were in areas where kids went door-to-door - I doubt I bought candy more than half a dozen years.
It’s obviously not a big deal event for me.
0$. I don’t do Halloween, anymore. If I have to go to a party I wear a scarf and say I’m a rabbi.
My five-year-old wants us to decorate the house for Halloween, but he’s afraid of anything spooky. Not sure how this is going to play out, but I know it will be expensive. 
When Little Pianola and Little Banjo were actually LITTLE, we did the rounds with them and didn’t give out candy. We did give out candy for a few years, but seemed to get as many burly teenagers (16-18) as cute little kids, so we shut off the tap.
Halloween is HUGE in Park Slope. Our Halloween parade is second only to the Greenwich Village one in all of NYC…but more child-friendly. For costumes I would raid my closet, wear 1920s-style clothing and carry a cornet and be Bix Beiderbecke, or wear 1930s-style clothing and carry a trumpet and be Bunny Berigan. I’d spend a week getting up my chops on a simple jazz/blues tune like “St. James Infirmary” or “Memphis Blues” or “I Can’t get Started” so I could knock off a quick solo if someone asked if I could really play that thing.
Most years = $0
In my little town, there’s a neighborhood where everybody — and I mean that literally — goes to trick-or-treat. I don’t live in that neighborhood, so I don’t buy candy. My daughter hasn’t lived with me for the past few autumns, so I don’t know what my wife spent/spends on her costume. A few years ago I bought a costume for IIRC $25. This year I’ve spent about the same, maybe $30 or so.
Probably around $30 for candy to hand out to the trick-or-treaters.
Plus, friends of ours host a costume party every year. It usually has a theme, and my wife and I sometimes wind up having to buy a few things for our costumes. That never adds up to more than an additional $75 or so.
We don’t decorate the house for Halloween, nor do we have children to dress up…and the cat would murder us in our sleep if we tried to dress him up. 
I spend a few dollars on a couple bags of candy.
I’ll also dress up in a slutty schoolgirl costume but that’s not a Halloween thing.
When I was younger, single and carefree, maybe $1,000/year. Friends threw a crazy wild Halloween party in upstate New York that was attended by friends from around the world. Between airfare, car rental, costume rental, hotels, etc., it was expensive but also An Event and a vacation, so well worth it. Good times.
In years when I was married and lived in a more suburban setting, maybe $200/year. That was for good candy to hand out to many kids in a neighborhood where families brought their youngsters to trick or treat, and costumes for hubby and me for whatever party we would attend that year. Also very fun. Never did the whole decorate-the-property thing, though.
Now I keep a crisp $50 bill for whatever kid is intrepid enough to make his/her way around the Munster-family style gate, down the long, dark, scary wholly-unlit quarter mile drive shrouded by hulking fir trees that crowd eagerly around the unwary traveler, over the two water crossings, past the eerie silence of the pond (or maybe you barely made out the sound of an unseen animal slipping around behind you) to approach the darkened door and ask for his/her treat. That kid deserves more than a candy bar.
I’ve had the same bill for 14 years.
Why weren’t they “allowed” in your condo? Did the condo close its gates or something?
My plans are to buy a $10 bag of candy and wonder if this will be the year when anybody actually shows up. The strange thing is, over the past 10 years, I have had next door neighbors with trick-or-treating-age kids, and even they don’t come to my door. I even have a collection of toothbrushes so I have something to give to their parents who insist on going with them…
