Login discover.com, use online chat(at the top right corner, Help->All contact info) and ask CSR for current available promo.
Many people including myself get the "get $10 CB when spending $200 in 30 days" promo, some get 0% APR for 12 months.
$10 is not a lot but not bad for a 5 minute chat.
As always, YMMV
For those for whom it didn't work. Try again. First rep did not offer anything - Second time was the charm.
While you're at it, ask for a credit limit increase without a hard inquiry. Just got my limit increased from $3000 to $4000
"A credit check with a hard inquiry is not always needed if you do the application with me via chat. However, if it is needed I will first ask for your permission before the inquiry is placed on your credit report. At that time you have the option to declined and withdraw the increase request without the credit check."
