How it works

Email s.n.psaradellis@gmail.com or use a link above. Name the city, a business type if you want one, and where you will use the list.
Every row is re-checked before it ships, so a site fixed since 2026-10-09 is dropped, not sold.
No personal email addresses are sold, and any business that asked not to be contacted is removed.
Pay by card after you have seen the free rows. $49 for the urgent-defect pack, $149 to keep the city to yourself for 90 days.
