Why on earth did you replace full number of sales in categories with “10K” shorthand?? It’s simply not readable! Now to see an exact number i need to open item page, but i don’t want to since i already see preview image.
If it’s A/B test - that’s fine. But if that’s the final change - it sucks. Really.
Items with big sales like that are often in the lasted pages that’s means to see them in the category page you have to select “Best Sellers” sort so customer will already except k means thousand
As a personal view I think keeping the sales number with limit characters could reduce the confuse and will raise the competition with the low sales items.
