A: You have to enter “in-stock” value for each item in the database. Upon each purchase number of items in stock will decrease. As soon as it hits zero - item goes out of sale. You can no longer purchase it through your website. You, as an administrator, will have to go back into the administrative area and change in-stock quantity for these out-of-stock items to some positive value. You do not need to have any advanced HTML skills in order to operate our shopping cart.
