>You would have been able to find those same tools and electronics, you may have had to just spend a few minutes browsing some sort of catalog.You may have read the gp's comment too quickly. The context was used tools and electronics from Craigslist ads.
The "used" would be pre-owned and less expensive, and "Craigslist" presumably means buying from a local seller.
Catalogs for tools and electronics are typically new items that are national in scope instead of local.
The Craigslist advertisements made him _aware_ of a local seller selling a used tool that he wanted.
What would be the non-advertising way to accomplish that same goal? Possibly driving to flea markets or swap meets every week? But the sellers with their wares on display are themselves a form of advertising. It's also an incredibly inefficient use of time to repeatedly drive to a location and walk away empty-handed compared to seeing a relevant Craigslist ad.
>some sort of catalog. The lack of advertisements wouldn't cause any serious difficulties.
Fyi in case you were unaware... Many retailers' catalogs are created with ad sponsorships to offset the cost of printing, mailing, etc.
