How to time a purchase with price history

Reading a price chart so you buy at a genuine low, not a guess.

Every product page on MyDealDrop has a price chart with two reference lines drawn on it: the 90-day average, and the 90-day low. Those two lines are the whole method — here's how to actually use them.

The average line tells you what "normal" looks like

A price sitting right on its own average isn't a deal — it's just the price. Nothing wrong with buying at it if you need the item now, but it's not a moment to feel like you've timed anything.

The low line tells you the best you can realistically hope for

If today's price is at or near the lowest we've ever recorded for that exact listing, that's about as good as it gets based on real evidence — not a promise it can't fall further, but a genuine signal that you're not obviously overpaying relative to its own history. Cards showing our Lowest ever pill are flagging exactly this.

Look at the shape, not just today's dot

A price that drops sharply then climbs back up on a regular cycle is telling you something: wait for the next cycle low rather than buying mid-climb. A price that's been falling steadily with no rebound is telling you something different — it might still have room to fall further, or it might have found its new normal. There's no universal rule here; the chart is the evidence, you make the call.

If you don't want to keep checking, set an alert instead

Every product page suggests target prices anchored to real numbers — the lowest we've recorded, or a percentage below today — rather than an empty box asking you to guess. Set one and we check on a schedule; you get an email when a check finds it hit, rather than needing to come back and look.
