Sam's Club is offering QuickBooks Desktop Pro 2018 with Enhanced Payroll (PC Disc) for $229 thru 1/28/18. While there are usually pricedrops closer to $189-199 range in January, this is the best price I could find currently and is $60 off the regular price.
For those with QB Pro and Payroll, this is a great deal IMO, even at $229. Last year, I dealt with the $400+ 'subscription' fee for payroll from Intuit to use the service a second year. With this, Intuit confirmed on the phone there would be no subscription fee for 12 months and that last's years' fees (paid in June) would be refunded on a prorated basis. By rebuying this annually, I believe that's where you'll find the real savings of hundreds of dollars, plus keeping your software up to date. Happy New Year!
Edit: Just noticed Amazon has matched this price for PC Disc version.
