What is the difference between unique and non-unique purchase?
NON-EXCLUSIVE or NON-UNIQUE PURCHASE:
Non-exclusive purchase means that other people can buy the template you have chosen some time later.
UNIQUE or EXCLUSIVE PURCHASE:
Exclusive purchase guarantees that you are the last person to buy this template. After an exclusive purchase occurs the
template is being permanently removed from the sales directory and will never be available to other customers again. Only you and people who bought the template before you will own it.
Is it reasonable to make unique purchase of template that was already purchased before?
Yes. Because there is very small chance that you will find the same design on the net. There are more than
3,000,000,000 webpages online now according to statistics on google.com.
