User Membership

Is there an extension to apply users when purchasing an item into a special membership for a certain amount of time?

Not that I am aware of,  however this is one called Rewards Points  that might work for you.  Just look in the extension store

one more extension Customer Group Update (Customer Loyalty) allows to set up auto-update of Customer Group based on total amount spent by customers.
