Please help me out here. finding a vibrator?

hi. i have just turned 18 and still dont have a credit card. i would like to buy a vibrator but because of the credit card thing i cant buy it online. i really do not wanna go to some store to buy one. does anyone know some brand names of regular magers that can be used for mastribation and that work well? iv tried a few but they never work well. preferably ones that can be bought at more common stores, but any would be good. thanks. oh btw im a girl
