Hi Sizam,

1) Since the last update the offer old price in post grid in columns is disappeared, the post grid in columns is only showing the offer sales price now. How can I get the offer old price back in the post?(the post showes offer sales price AND offer old price).

2) How can I have the “percentages off” in the right top of the post?

3) When one of the titles in my post grid in columns got two lines, the prices on the row of post grid in columns are not at the same line(height) anymore. How can I secure the prices in the bottem of the post, so the prices are on the same height/line?

Sincerly,

Sander
