Hello Elias,
Thank you for your response and thanks for the compliment for my site.
I tried to resolve with my previous problem (How reduce the product sizes from my collection page) with an agent but it wasn’t very helpful but I got some solution from somebody else here Shopify Community. I played with the numbers from the original css and tried to add right alignment but it didn’t work well. I’ll try to reach the Shopify agent again but I don’t expect much.
I’ll check the marketing plan you suggested. It’s the most difficult part ever! LOL
