The catalog has items set at a 50% discount, but what if I want to increase or decrease the default pricing?
Great question. Start by using the pre-built catalogs to add items to your sale, Then, if you've upgraded to PRO, you'll see a % icon in the upper right corner of each of your category headers. Click on that icon and you'll see the option to increase or decrease all items within that category by the percentage of your choosing. Do this for all categories that you wish, and in a matter of clicks, you will adjust pricing for every item on your sale.
Pro Tip: The easiest way to change the percentage off is to increase the price back to original retail price (in the case of 50% off, you would increase by 100%) and then decrease the retail price by the percentage you want off (40%, 60% or 70% etc.).
