Kit & Co. review for Discount Master ‑ Quantity

I used this app to organise a sale campaign which changed the discount each day. It was really clunky and slow to process the 600+ products. Each day I had to delete the current campaign (instead of editing it) and then start a new one... I have thousands of low value products, so it ended up costing me extra, as the paid level only allows for 1000 discounts... but they accumulate, it's not 1000 at once. Didn't love it.
