Main functions
On Product prices-tab we have different prices for a product and its variations. The main functions are:

1. Same price regardless of color
This checkbox is used to "collapse" price rows for simplified view. Useful in case you don't have different prices between color variations.
2. Same price regardless of size
Same as above but with size variation.
3. Filter
Filter function to view only the rows containing value entered here.
4. Add new price row(s)
With this button you can add new price rows for a product.
5. Delete
Delete selected row(s)
6. Variation prices
Warning sign here indicates there are different prices between variations. Click on the checkboxes (1) or (2) to see all price variations.
