Lowmark

That "sale" is only a sale if it beats what you normally pay. Lowmark remembers your prices, does the unit-price math, and tells you: buy, wait, or stock up.

A flyer knows what the store is charging. It does not know what YOU normally pay.

That is the whole problem with grocery deals. "2 for $5" looks great until your own records show you usually pay $2.19 each. Lowmark keeps those records, so you can tell a real bargain from a sticker.

KNOW A GOOD PRICE WHEN YOU SEE ONE After a few entries, Lowmark works out your low mark — the level a genuinely good sale reaches for the things YOU buy. Then every price gets a straight answer: Stock up, Good price, or Wait, with the reason in plain English.

THE UNIT PRICE, DONE PROPERLY An 18 oz jar at $2.00 or a 16 oz at $1.80? Ounces against pounds, liters against fluid ounces, six-packs against singles. Lowmark converts everything to one basis so the comparison is real. The bigger box is not always cheaper, and now you will know.

WHAT A DEAL ACTUALLY COSTS Buy-one-get-one on a $5.99 item is $3.00 a unit. Three for $5 is $1.67. A dollar-off coupon on a small pack can beat a bulk price. Lowmark does that arithmetic for coupons, BOGO, multi-buys and percent-off — then checks the result against your own history. It also tells you how many you must buy for the deal to pay, because two tubs of yogurt you throw away is not a saving.

WHERE IT IS CHEAPEST See every store you have logged, ranked by real unit price, with how much more the others cost and the date you saw each one. Nothing is ever presented as today's price, because we cannot know that.

WHEN IT WILL BE CHEAP AGAIN Most groceries move in cycles. Once Lowmark has seen a few lows for an item, it estimates the rhythm — so "buy it now" can become "buy one now, it will be low again in three weeks."

A RUNNING TOTAL WHILE YOU SHOP Start a trip and add items as they go in the cart. See the total before the till, and each item checked against your book as you add it. Every entry updates your price book automatically, so it never goes stale.

SAVINGS YOU CAN ACTUALLY DEFEND Two numbers, kept apart on purpose. Money off at the till from coupons and deals — that is a fact. And how your prices compared with what you usually pay — that is an estimate, and we label it as one. Per trip, week, month or year, with charts.

YOUR COUPON DRAWER Keep the offers you actually have, with expiry reminders so they do not die in a drawer. Lowmark does not download deals from stores — so nothing here is ever silently out of date.
