Don't do it. It does not help your: 1. Marketing 2. Sales 3. Customer satisfaction It brings in uncertainty in your financial breakdown. It's silly, if you want to do silly things, do it in marketing, as they can have a positive effect there, but not in the way you close your sales. Your price is the end of the pipeline, don't mess with a customer that is already that far down your sales funnel. I notice for example that if I absorb the tax on my products, it bumps up sales by over 90%, but if I decrease the price so that the tax does not matter, the rise in sales is about 5%. This is because of the no-suprise philosophy. A person who is clicking through your shop likely wants to buy. When you suprise him at the end with an additional fee, you lose him.
