My personal shopper.

Will work for fishies, crackers, chocolate, basically anything in the form of food. She prefers to wear panties rather then pants and loves to wear her princess high heels. She'll get you anything on your list and loves a good bargain. She likes to clip out the coupons herself and will find the best price... 

But, beware - she will charge you a large Icee before her shopping adventure and will ask to walk half way through the store. But, in my opinion... she's the best personal shopper out there!
