Read the original ↗Part 1 · What the source did
A first Grok Bot routine: scan a marketplace every morning for unusually cheap tech. The original also messages sellers; our version drafts messages for you to send.
- Set up a daily routine that searches Facebook Marketplace for tech deals.
- Has the bot message sellers (our version adds an approval step).

Part 2 · Our copy-paste version
Adapted by us from what the source described. Fill in the [BRACKETS].
The prompt
Every morning: search [MARKETPLACE] within [RADIUS] of [AREA] for [ITEMS]. Flag listings at least [30]% below typical used price (show how you estimated it).
For each: title, price, typical price, link, red flags (stock photos, no pickup, pay-first).
Draft a polite message for each, but DO NOT send. I'll pick which ones to send.
🛡
Approval ruleDrafts only. You send or approve each message to a seller.
Set it up
- Log the box browser into the marketplace yourself.
- Run once and judge the deals.
- Save as a routine.
Common failures
⚠
What usually goes wrong
- Scam listings look like great deals; keep red-flag checks.
- Marketplaces limit automated browsing; keep volume low.
Variations
- Add a price ceiling per item.
