One interesting thing about Accumulation is that the first day or so were almost guaranteed to be the hardest. The lost deposit from just one failed auction could ruin her; leave her unable to list anything else, and end this experiment before it began. Think I'm kidding? By selling everything she owned, Accumulation managed to begin with a grand total of... 18 copper.
EIGHTEEN. This was gonna be harder than I thought.

Before I continue, a quick word about my addons. I do have the auctioneer suite installed, but I am using it STRICTLY for the UI enhancements. I am doing
no automated purchasing of
any kind. Every single transaction is and will always be 100% manual.
Anyway, because of the risk inherent in listing items (as I outlined above), I decided my initial strategy would be to look for an item available for buyout for a price lower than what it vendors for. A longshot? Maybe. But what other choice did Accumulation have?
In the end... SUCCESS! By sorting items by buyout price (low to high), I was able to find a Light Feather available for a 4c buyout, and Light Feathers vendor for 7c. BWA HA HA... Accumulation now had 21c to her name. Using this, I was able to quickly snatch up two Mining Picks for 20c, and vendor them for 32.
From there, things moved a little more quickly. Another Mining Pick, some Spider Ichor, Shiny Fish Scales... Accumulation had more than tripled her money!
It didn't take long for my options to be exhausted, however. I quickly hit a wall, having bought out everything I could afford that had a higher vendor price. I closed out my (in my opinion) successful initial foray by placing very low bids on items that will turn a significant profit, should the auction close before I'm outbid. My complete Auction history, for the day:

All the the items above were purchased to be vendored - none were relisted.
My total bankroll, including current bids. If the Mark, Blackmouth, or pants come through, it'll be HUGE:
Beginning bankroll: 18c
Ending Bankroll: 72c
