For me i just let it run on its own. Random shop work well for me. My guess is each shop has items that can sell for profit. IMO AB will slowly stack your money up into a snowball
My brother told me that using the money using the money to spend on AB is better as sometimes stockmarkets as sometimes stockmarket could take quite sometime to rise. Is that true?
And also selling item at auction or buying from auction is the right way to earn?
