How it works

A price on its own tells you nothing. $160 for a running shoe — is that a deal or full price? The answer is in its past, and that past is what RUNDEALO keeps.

We read prices at the source, every day

For every product we track, we read the retailer’s own product page — no feed, no middleman. The price shown here is the one on that page at our last check, and our link sends you to that exact page.

Checks are spaced several seconds apart and spread through the day: we never put load on a retailer’s site.

We keep the history, and that is the whole point

Every time a price actually changes, we record it. We write nothing when the price hasn’t moved — a price history should describe the market, not our robot’s schedule.

That memory gives three numbers you won’t find on the retailer’s page: the usual price, the lowest ever seen, and how today compares to both.

The signal

Once a product has enough history for us to have an opinion, it carries a verdict:

• Good time to buy — the price sits at its known low, and that low is genuinely below the usual price.
• Price just dropped — a clear fall from the usual price.
• No verdict — either the price is normal, or we don’t have enough history yet. In that case we say nothing rather than invent something.

What we don’t do

• We sell nothing. RUNDEALO has no cart, no stock, no after-sales service. You buy from the retailer, on their terms.
• We never invent a price. If a check fails we record nothing: a gap in the history beats a wrong number.
• We don’t show stale prices. Past seven days without a check, a product leaves the grid until the next one.
• We don’t rank by what pays us. The order of prices is the order of prices.
