It is very common these days to have some sort of extra information in between the products on the collection page. For example the USP's in between the lines. Or even when going crazy you might want to advertise a specific product/ discount in there?
In my opinion the USP's are essential to have in between some of the rows on the collections. Most of the time is spend scrolling on collection pages so giving that extra little information could definitely boosts conversion.
Thanks.
Keep up the good work!
