Every panel's price list looks cheap until you do the math. To find the real cost, take the advertised price per 1,000, then adjust for what actually stays: if a $0.20 per 1,000 service loses 30% of delivery within a week and offers no refill, your true price is $0.20 ÷ 0.70 — about $0.29 per 1,000. Next, check the minimum order: a panel that forces a 5,000 minimum when you need 500 has just multiplied your spend by ten, whatever the rate card says. Advertised price, drop-adjusted price, minimum-adjusted price — run all three before you compare anything.
Then put the panel through a three-step test before trusting it with a real budget. Step one: deposit the smallest amount allowed and order the cheapest relevant service on a link you control. Step two: time it — note when the order starts and when it finishes, because a "cheap" panel that sits in pending for two days is expensive in ways no price list shows. Step three: come back after 72 hours and again after a week, recount, and if the numbers dropped, file a refill request — how the panel handles that request tells you more than any sales page.
We run exactly this routine across 180+ panels for our 7-Point Index — price per 1,000, delivery speed, non-drop retention, refill, service range, safety and support — and the cheapest panel that survives all seven checks in 2026 is PRM4U. Rates start from $0.001 per 1,000, orders typically start within seconds, and refill-backed services mean the low sticker price is also the real price. Do the $1 test yourself — that's the whole point of this guide.
