How can I go to a store to buy a vibrator without feeling awkward and embarred?

There is a CVS store that is in my hometown and when I was there one time I saw a vibrator that I saw on TV and I heard there was good reviews about it so I would like to give it a try. I don't want to feel awkward or embarred to buy one and I don't want anyone else to know about it. I was thinking about wearing sungles so I can disguise myself LOL.
