I couldn't find a direct link to the credit card promotion anywhere so I just used the link for what I bought.
If you add an item to your cart at Newegg you'll see an offer in the cart for an Amex credit card. If you apply to and are accepted for the Amex Everyday credit card, you can receive the card number digitally and use it right away even though you don't physically have the card yet.
The promo offers $25 back as a statement credit on any Newegg purchase of $25 or more as long as you buy within 3 months of approval. The credit takes 6-8 weeks to come back to you but I think this is still a good deal. You also get a free year of Newegg Premier if accepted.
You can get the Crucial MX500 500GB SSD for $65 (which is Shoprunner eligible), or alternatively you can get $25 off whatever else from Newegg as long as it's over $25
