Re: Money Question
Regarding buying and selling stock to the same shopkeep... if the number is green, it doesn't necessarily mean that particular shopkeep will buy it back for more, resulting in profit for you. The secondary number (the one in brackets), is the average selling price for that item across Albion. A green number indicates that you can sell that item *somewhere* in Albion for a profit. To find out what items you benefit from with each shopkeep, you have to try every item and remember them yourself. I personally (early in the game, anyway) prefer to go to the trader in Bowerstone South and buy out all his apples, apple pie, and (I think) cider crates (been awhile since I've done this). Then sleep until his next shipment, buy him out again, and continue on this path until you have a few hundred of each item. THEN sell them all back to him, and buy, sell, buy, sell, etc.
As for the Temple of Avo exploit...
There is a minor glitch in the game, where if you donate your money, then rapidly push your 'A' button, it selects the font again before they've had a chance to drain your money. You still get all the good points, and anything they want to give you (the title Paladin, youth, or the Sentinus), but don't lose your money! 1AK is right though, in that it doesn't always work. I highly recommend saving before trying it, and again between each attempt, if it DOES work.
And finally, how much money do I have? Well, I cheat alot of shopkeeps out of money, and I killed everyone in Oakvale.... I think I'm somewhere around 4.5 million....
I know, I liked your two cents. It reminded me of where I got my info from lol
