5 Things to Consider When Raising Prices
The bottom line is to have integrity, be prepared with a plan, and be ready with a solid answer for customers.

Train your sales people to be able to handle objections or attack it head on if you believe the increase will be noticed.
I hope this helps, and good luck with your price adjustment strategies.
