In for a radio + earbuds. Swinging for the fences for both cables and hope both in stock before the coupon expiration of 6/16. Doubtful though.
For rebates processed by Newegg:
OK to buy multiple rebate items on one order
One rebate form per item (even if purchase quantity/limit > 1)
For rebate with different items, submit one rebate ONLY IF they are all purchased in one single order
One form per envelope
Newegg coupon or gift card will not affect rebate
Limit one rebate per item (quantity may be >1 if allowed) per promotion period: you'll be eligible for a rebate IF they have different promo numbers (except for certain antivirus)
