It's October and for many people that means Halloween and haunted houses.I've found deal to several haunted houses in the metro area, but you'll need to buy quickly to get in on some of the specials. Groupon is offering discount VIP fastpasses/tickets to 13th Floor and Blood Shed. Two tickets are $37. The regular price for two tickets is $60, according to the Blood Shed website. Sale ends at midnight on Tuesday. Crowd Savings is offering VIP tickets to Frightmare for $12. Frightmare's website says general admission is normally $20, VIP admission is $30. The sale ends late Wednesday night.Interestingly, both Groupon and Crowd Savings are listing an "original" price that is different that the haunted houses' own websites. That's a good reminder that you should always check to make sure the deal is as good as it sounds. Denver Daily Deals is offering $10 tickets to Chaos House of Pain. Denver Daily Deals says the normal ticket price is $20. I tried to find the Chaos house of Pain website, but I only found lots of sites offering deals for the haunted house, not the actually haunted house's website. To get this deal, you must purchase your tickets by Tuesday night. Boulder Daily Deal is offering two tickets to the Circus of Fear in Westminster for $15. The Circus of Fear website says the normal general admission price for two people is $30. The deal ends Monday night.Check out all the daily deals in one place on MileHighontheCheap.com.If you see a deal, e-mail me Debbie (Debbie@thedenverchannel.com).Get the latest deals by following me on Facebook, Twitter @DebbiesDeals or sign up for a daily e-mail alert by visiting our e-mail alerts page.
