Hello there, marquez,
You might have availed the discounted prices when you opted to Buy Now instead of going through the one-month free trial. For the first three months of your subscription, we offer it. Right after that, you'll be charged the regular rate.
You can check that here, https://quickbooks.intuit.com/self-employed/.
Furthermore, price increase is essential for the product enhancements. There will be feature updates soon for better experience in using QuickBooks Self-Employed.
Let me know if you have other feedback, I'll be hear to list them for you.
