This disclosure provides a portable shopping aid used to mount a shopping list, coupons, or other documents. Contrary to conventional wisdom, the aid is configured to sacrifice a writing surface in favor of portability, by providing a small body that may be easily inserted into a pocket or handbag. The body includes a clamp for mounting the aid onto a push bar of a shopping cart, for hands free viewing during shopping, as well as a document clip mechanism that clips documents by their ends closest to the push bar. In order to provide structural rigidity to retained documents, and notwithstanding the absence of a writing surface or clipboard, the clip mechanism is configured to crease documents. The shopping aid also includes feet for standing the aid upright, on a flat surface, and means for mounting the aid magnetically on a refrigerator wall, in all cases such that retained documents are presented in a convenient reading orientation. The aid is further designed so that it can be made in a single mold, thereby lowering design costs.
