Cart Logic

Fill your cart with the genuinely cheapest option per unit, stay under budget, and flag the single fake bargain whose claim doesn't add up.

How to play

Each item on the shelf offers several pack sizes, coupons and flashy tags. Your job is to choose the best true value per unit for every item, keep the total under budget, and spot the one deal whose advertised saving is a lie. Get all three right at checkout to clear the round.

• Pick the lowest genuine price per unit for each item
• Keep your spend under the budget
• Flag exactly one fake deal per round
• Check out only when every item is chosen

Controls

• Desktop: click an option to add it to the cart, click the flag icon to mark a fake deal, then Check Out.
• Phone & tablet: tap options and the flag, then tap Check Out — touch supported.

Game modes

• Daily: one shared seeded shelf per day
• Practice: fresh shelves at Easy, Medium or Hard

Tips & strategy

• Always compare the per-unit price, never the pack price — bigger isn't automatically cheaper
• Apply the coupon math before deciding; a percentage off a small pack can beat a dollar off a big one
• The flashiest tag is usually the fake — verify its claimed saving against the real unit cost
