Thanksgiving is coming up and I want to offer 30% off all items on my site for Black Friday through to Tuesday 2nd Dec. Is there an app that can:
Adjust all the prices at a time specified by me (automated in advance)
Put the old price in the Compare To field
Change prices back and remove Compare To price at a time I set it to do so?
I've looked through the app store and haven't found anything yet.
Instant Bulk Discount & Sales app exactly what you need. Unlike other discount apps, it applies discounts for thousands of products in a few seconds. You don't need to wait for hours to activate discounts.
I know the thread is old but I recently developed an app for this purpose: "Ahia! - Easy Price Changer".
You can find it here: https://apps.shopify.com/ahia-easy-price-changer
You can do a lot of things with it:
A lot of new features are being developed and will be released soon.
