The first vendor I hit is the toy vendor. Here, you can buy a stack or ten of each, and just leave them in your bank picking them up here and there when they sell in the AH, and try to keep 2 up at all times. Since these are mere silver to purchase, they aren't too much of a profit (I usually sell them for 20ish, but since Cata they are 100+g).

Zippy Copper Racer bought for: 30s
Trusty Copper Racer bought for: 30s
Grindgear Toy Gorilla bought for: 45s
The next vendor is right next door, and here you will invest a bit more gold, however the return is much higher (as you can see in the auctioneer details). Also take a look at how many have been in the AH (I reset my auctioneer files when cata hit, which I hope you did as well), very few, as [currently] I am the only seller. =)

And last but not least.....I have been caught.

I guess when I started writing this blog I didn't realize that people would read it, let alone find my toon. When I received the tell, I am not sure what was funnier: that someone actually read my blog or that someone laughed about me being the author. Out loud. Haha.
But I figured that since they were the first to find me they got my coveted 1K card. Who will find me next? Maybe I should change the blog title to Waldo's Gold"ish" advise...
