A spy tool is only worth its invoice if its index is alive, so each audit checks three things on the review date: (1) whether the ads surfaced in a sampled query actually ran within the last 7 days on TikTok, Meta or native networks; (2) whether SKU "order curves" from tools like FindNiche match live AliExpress / Shopify listing counts; (3) whether the plan tier's credit limits allow one full day of creative sampling before paying. Everything above is list pricing read from each vendor's own pricing page in ; partner-link auto-applied discounts and free-trial credits shown in the notice above are additive to these list prices.
The cheapest verified working stack for Shopify & TikTok Shop sellers stays BigSpy $9/mo Basic (FB/IG; $99/mo Pro for TikTok & 9 networks) + FindNiche $12/mo Basic on classic.findniche.com (main site free) = $21/mo; add Voluum $199/mo only once spend passes ~$10k/mo.
