Buying a dildo...

I'm 18, I don't want to settle down with a guy because I'm about to go off to college in less than a year and don't want to get attached then have it be ripped apart because of distance.. but, I have a major sex drive and have been thinking about getting a dildo. I don't want the awkwardness of going to a store and buying one but I can't have it delivered to the house in suspicious packaging. My mom can also see how much money I've spent and what store it was at... any suggestions on how to go about this?
