So I opened the account in May and I got an automatic increase to my credit limit on 8/27, 3 months after I opened the account.  Today, I logged into my account saw another automatic limit increase effective 11/27, exactly three months later.  My line of credit with Discover started at $1,000 and was increased to $1,350 in August and $1,700 now.  Not huge but, I'll take it considering two years ago the only card I could get was a $300.00 Direct Merchants Bank Discover.
