To alter the 'Product Markup Rules', from the store dashboard go to: 

> Store Settings > Products > Markup Rules

From within this page you may select the price ranges of products you would like to increase the markup on. You can do this with the use of the 'From' and 'To' fields:

For example, if we wanted to create a markup on products ranging 'From' 1.00 USD 'To' 5.00 USD, we would make the following alterations:

The 'Price or Formula' field to the right dictates how much products ranging 'From' 1.00 USD 'To' 5.00 USD are marked up by: 

You can either:

1. Add a fixed price such as 5.00 (if the product originally costed 2.00 USD, this would make the price $7.00)

2. Add a multiplication sum such as * 2 (if the product originally costed 2.00 USD, this would make the price $4.00)

3. Add a combination of both * 2 + 5.00 (if the product originally costed 2.00 USD, this would make the price $9.00)

Lastly, the field at the end labelled 'Discount' can provide a reduced sale cost of your products within that price range (if set):

For example, if the product costed 2.00 USD and we added a 10% 'Discount', then the price would depreciate to $1.80. This can also be combined with the 'Price or Formula' field. 

*Please follow the 'Help' guide over to the right hand side of the page to make successful markups*

From within this page on the right hand side, you will find a 'Help' guide which will inform you what each option entails. Click 'Save Changes' to confirm the new alterations.

To add more markup rules, click 'Add row' at the bottom:

After applying the relevant markup rules, the part of the price after the decimal point can be changed too:

Can either be:

• A specific number, e.g. 99, so an example price of 8.78 becomes 8.99 
• Multiple numbers separated by commas, e.g. 95, 97, 99, are applied randomly to each applicable product
• Nothing (blank) to make no change to the price given by the markup rule 

If you decide to update all the prices with the markup rules you have set, you can do by clicking 'Update all prices using the current markup rules':
