this is expanding by the daily, i hope bitinstant manage to break through
I found their web site (Bitinstant), but am not sure what to make of it. Can I use my Chase Bank account to buy bitcoins through them?
Yes. set up an account account at Mt. Gox or one of the other "send to" options. (unless you already have).
Follow the instructions on bitinstant. select major bank and print the slip your are given.
You then have 3 days to go into your bank and transfer the money. Once you have it should take only mins. to go through.
