I've never seen this posted before, I searched, found nothing at the very least it is a helpful repost for those who've never seen it before.

Okay so here it is. In CoT Old Hillsbrad (Durnhold Keep) there are two vendors (that I saw) who walk around. One of these vendors sells the pattern for riding crop. You can sell this for up to 15g, and the vendor sells it (unlimited) for 5g. Most people know about this however, so it's not too useful. This same vendor also sells shirts and the level 1 gear. The level 1 shirts (especially the other faction's) sell for up to 50s each. The vendor sells them for under 1s (55c I believe). This can make you quite a bit of practically free money.
The other vendor sells a enchanting formula. Most people don't know about the other things these vendors sell, as they only want to purchase the riding crop pattern.
These vendors walk around on the paths.
Thanks for reading, I hope you found it helpful, informative and useful.
