How many products can I add in a block?

You can add all products or just a section from the Product catalog to blocks containing cards (ST300, ST305N, ST310N, ST315N) from the "Store" category.

You can add up to 5 000 items on Personal plan, and 50 000 items on Business plan. To make navigation smoother, it can be a good idea to group your products into different categories up to 100-200 items and display them in blocks on separate pages.
