ADD TO CART BUTTON ON COLLECTION PAGE
Depending on the business, sometimes a customer already knows what they're looking for, or has previously shopped and made the decision, and being able to "grab and check out" is convenient.
If you are doing grocery shopping, YES
Its good to have Add to cart and Quick View both the buttons on product listing.
Moreover, it depends a lot on targeted market and behaviour of shopping. i.e I mentioned If you are selling online groceries, It makes lot of sense to put the "Add to cart" button on listing page because probability of buying multiple items is very very high. Its like the way you buy offline groceries. You pick an item and put it in cart.
What you want is the best possible click-to-sale conversion rate. Why remove the chance for a customer to add something to their cart at the earliest possible point? Or in other words, why require the customer to drill down into the details to add the item to their cart? If they know what they want.
