As a part of this new slew of Origin client-only promo codes, Mass Effect 3 preorders (standard edition pc digital download only) made through the Origin client will net you $20 of credit towards future purchases at Origin. If you want promotional credit for physical copies of the standard edition (pc, xbox, ps3), Amazon.com is still currently your best bet with a $10 promotional credit towards future video game purchases. More about the fine print and caveats after the break.
Here's the fine print of the offer:
*Offer expires October 27, 2011. Code expires date November 14, 2011. Valid only for new purchases valued at $40 or more. Valid only at Origin store at store.origin.com. Customers will be emailed the code within 10 days of purchase. Offer may not be substituted, exchanged, sold or redeemed for cash or other goods or services. Valid only in U.S., Canada. May not be combined with any other offer, gift card, rebate or discount coupon. Void where prohibited, taxed or restricted by law. Internet connection and EA/Origin account required. You must be 13+. EA may retire online features after 30 days’ notice posted on www.ea.com/2/service-updates. PC product requires acceptance of end user license agreement. Access to pc online features limited to one EA account.
Does this mean that the $20 credit you receive expires on November 14th? That's not a long time to spend it, especially if they take up to 10 days to email the code to you after purchase... Unless you have another purchase in mind already for the credit (another preorder, perhaps?), this expiration date might be a deal breaker.
For instant rebates/direct discounts to preorders instead of promotional credit, I would keep an eye on digital distributors for discount promotions that apply to preorders. I mentioned one about 25% off Mass Effect 3 pc digital download preorders earlier this year ($45), long since expired, so you never know when or if it might happen again (D2D ownership may have changed hands since then, lessening our chances...it has been a while since we've seen a general use code at their site). At least, you've still got until March 6, 2012 to find something.
