While I'm not sure which coupon you'd be referring to, the terms and conditions which can be found on the coupon/coupon page directly usually state: "Coupon cannot be combined with other offers." so this would not be an option.
Ian, is there a way I can private message you or contact you directly? No terms/conditions are with the coupon. I am being intentionally vague as to not bring attention to what is likely an error on Micro Center's part.
I will send you an email to collect more information about this.
