LPT: If you're selling something on Craigslist, put your phone number in the first image

Like this! Then you can just say "text the number in the first image if you're interested.

If you put your number in the body or under the contact details section you will likely be overwhelmed with spam texts, and it can be extremely frustrating. I recently sold a car this way and 100% of the texts I received were real people- I was quite pleased with the results. :)
