I recently listed some items on sale using Markdown Manager. Last month when I went to revise and discount the items that were on sale it let me do so while still keeping the original price and now showing the new sale price. So for instance I had an item markdown 5% then I revised it and made it say 12%. So the new sale price was there with the orignal price in the background.
Now when I try revising a sale price it cancels the sale and marks the item down. My question is how can I further discount items on sale while still keeping my orignal price as well behind it? Is there a time period I have to wait before doing so from the orginal start date of the sale?
