Mia marched into the neighborhood grocery store with her ten-dollar bill held tight in her fist. She headed straight for the candy aisle, grabbed a bag of gummy worms and a box of chocolate cookies, then counted her change at the register — only two dollars left. She stared at the empty space on the counter where her treats should be.
Her mom knelt beside the cart and opened a notebook labeled 'Prices,' revealing old receipts pinned inside with numbers that made Mia's eyes widen. She traced the dates with her finger and noticed every category had climbed, so she slammed the notebook shut and declared she was going to investigate.
Mia followed a delivery truck to a warehouse where a worker showed her crates of supplies stacked floor to ceiling. He explained that fuel costs more and shipping routes have changed, so everything arrives pricier, but Mia scribbled furiously in her notebook until her pencil snapped in half.
Back in the grocery store, Mia compared old price tags with new ones, then spotted a 'Sale' sign that made her heart leap — until she read the fine print and realized the original price was inflated first. She held up two nearly identical jars of peanut butter, one twice the price of the other.
Mia whispered, 'They tricked me,' as she tucked a folded receipt into her pocket and marched toward the exit. The summer sun beat down on the parking lot as she walked home with her notebook pressed close to her chest.
Mia returned home and pinned her evidence board on the kitchen wall — receipts, photos, and a hand-drawn diagram of the supply chain with arrows connecting everything. She stepped back to study her work while the kitchen clock ticked softly in the background.
Her mom poured them both a glass of milk and raised her glass in a toast to the Price Detective. Mia grinned back, her detective work complete, as the afternoon light streamed through the window.
Mia flipped open her notebook to a fresh page labeled 'Next Case' and uncapped her pencil, ready for whatever mystery came next. She took a long sip of milk and began to write, her brow furrowed in concentration.
