I have not been having much luck with the trading post,
armour flipping in particular. One of the things I am not sure about is
how you choose which armour items to purchase, and also how many of them
to buy. Are lower priced items (below 1 silver) better to invest in
than higher value ones such as over 10 silver or a few gold and how can
you tell if the item that you are buying is going to make you a good
profit, or just not sell at all? Any help on this would be much
I stick to the low level fine and masterwork items (sub level 30).
Anything with attack power or vitality will always sell, but in
actuality I haven't found an item that didn't eventually sell. Remember that everything scales in WvWvW, so there is more incentive to buy items with good stats.
I used to place buy orders on the ones that made me a few silver, like
1-2 profit each. I would take whatever I managed to buy (usually buy
orders of 5) and sell 1-2 at a time.
Honestly, at this point in the game, I almost don't care what stats they have, I just care about how much I'll make selling them. Definitely look into buying the ones that make you like 20-60 copper because they sell really quick.
