A shopping system (100) for tracking and tabulating costs during a shopping experience, wherein the system (100) comprises:
- (a) a shopping cart (110), wherein the shopping cart (110) comprises a handle (120) having a handle diameter (121) and a horizontal support bar (125) having a horizontal support bar diameter (126), wherein the horizontal support bar (125) is disposed below and offset from the handle (120);
- (b) a computing unit (130) having a computing unit top (131), a computing unit bottom (132), and a computing unit front (133), wherein the computing unit (130) comprises:
- (i) a power supply (140) disposed therein,
- (ii) a microprocessor (145) disposed therein operatively connected to the power supply (140),
- (iii) input keys (150) disposed on a computing unit top (131), wherein the input keys (150) are in communication with the microprocessor (145) for data input,
- (iv) a first display (155) and a second display (160) disposed on the computing unit top (131), wherein the first display (155) is operatively connected to the microprocessor (145), wherein data input from the input keys (150) is displayed on the first display (155), wherein the second display (160) is operatively connected to the microprocessor (145), and
- (v) a scanner disposed on the computing unit front (133), wherein the scanner is operatively connected to the microprocessor (145), wherein data read by the scanner is displayed on the second display (160),
- (c) a first clip (170) disposed on the computing unit bottom (132), wherein the first clip (170) is adapted to snap onto the handle (120), wherein a first clip inner diameter (171) is equal to the handle diameter (121), wherein the first clip (170) comprises a first clip opening (172), wherein the first clip opening (172) opens away from and perpendicularly opposite from the computing unit bottom (132), wherein the handle (120) is insertable into the first clip (170) only from the direction that is perpendicular to the computing unit bottom (132), wherein the first clip (170) rotates about the handle (120);
- and
- (d) a second clip (175) disposed on the computing unit bottom (132), wherein the second clip (175) is adapted to snap onto the horizontal support bar (125), wherein a second clip inner diameter (176) is equal to the horizontal support bar diameter (126), wherein the second clip (175) comprises a second clip opening (177), wherein the second clip opening opens perpendicular to the opening on the first clip (170), wherein the horizontal support bar (125) is insertable into the second clip (175) only from a direction that is parallel to the computing unit bottom (132), wherein the first clip (170) rotates about the handle (120) until the second clip (175) is snapped onto the horizontal support bar (125);
- wherein data pertaining to the shopping experience is entered into the microprocessor (145) via the input keys (150), wherein data pertaining to the shopping experience is viewed through the first display (155), wherein the scanner is used to read information from an item for input into the microprocessor (145).
