A source is saved
The SparrowVolt owner saves a retailer product-page URL for a listing. That saved page is the source for its check.
SPARROWVOLT / RETAIL CHECKS
How retailer price and availability checks work
Published retailer details come from a saved product page checked when a SparrowVolt owner requests a refresh. Each result is a dated snapshot, not a live feed.
The owner starts a refresh
When the owner starts a refresh, SparrowVolt reads the saved page for that check. Pages are not checked in the background.
Each fact needs evidence
The listed product must match. Price and availability are verified separately against evidence on the retailer page.
What can change
Only supported facts are updated
SparrowVolt updates a price or availability only when evidence from the saved retailer page supports that fact for the listed product. The two facts are checked separately; if one cannot be verified, that fact keeps its saved value.
If the page cannot be read, or the check verifies neither fact, the saved facts and recorded check time stay unchanged.
Retailer purchases
The retailer handles the purchase
Retailer checkout, purchases, and their terms are handled by the retailer. SparrowVolt does not control retailer checkout, purchases, or refund policies, and does not sell or refund retailer items. Visit the retailer’s product page for current prices, availability, and applicable terms.
