The problem
A keyword match is not an opportunity.
One day of one saved search
Keyword matches 142
Manual comps needed 38
Margin-aware candidates 4
False positives in every saved search.
Asking prices never show the actual margin.
The best listings sell before you have checked the comps.

Questions
Quick answers.
How is this different from eBay saved search alerts?
A saved search fires on keywords. Adlert checks sold comps, condition signals, and your margin threshold first — you only hear about listings worth a buy/pass call.
