In order to have the price changes apply on a later date follow the below instructions before making price changes. 

1. Navigate to the Batch Editor

2. Add a batch.

3. Add a code, description, and the date you would like changes to take effect. You may also add notes here you can reference later. Click add.

4. Then, go to product manager. Click F11 on your keyboard and the menu at the bottom of the screen will turn red. Click 'Batch'.

5. The batch editor will appear. Select the batch you created, and click OK.

6. You will see some red text that says 'recording to *batch code*'. Change the price for each product you need updated on this date now. Once you have made the price changes, click 'Batch' again in the red menu at the bottom of product manager, and you will see the 'Regular Price' field highlighted red, indicated there is a price change waiting in the batch. (Please note, you can change other fields relating to the product in a batch as well, and the same process applies.)

7. Navigate back to the batch editor. Select your batch and click 'detail' to review. 

8. Once you have reviewed the batch, if it looks correct click close, and change the batch status to 'approved (don't update label que)'. If you do not update this status, the price changes will not take effect!
