or, how to give your girl a unique present that will have her cooing to her friends about how sweet you are....and do it nearly for free. These ideas all include an inexpensive "wrappable" item along with the larger gift.
The wrappable: one of these neat purse hooks. The real gift: a promise to be her personal purse hook for a day....yes, that means holding it for her outside of dressing rooms! Commit to a full afternoon of holding her purse, schlepping her bags, fetching her water, and generally being supportive and complimentary while she browses her favorite stores.
The wrappable: this adorable robot earphone-splitter, which is under $10. The real gift: the modern equivalent of a mix-tape. Build and procure for her, through whatever means you use to get your music, the ultimate awesome playlist and load it on her iPod for her. Don't forget the cheesy title!
