To see your 'Add to Baskets', from the store dashboard go to:
> Baskets

From within this page you can see all the customers who added to basket but didn't checkout. With this information you can retarget those customers so that they remember to return to your store to continue with their purchase.
Clicking on a baskets 'ID' number will open up another page with more information about the basket:

Here you can learn what the customers email and/or phone number is, when the checkout process began, and what products were added to basket.
