The Ergobaby Options Carrier is a hot deal on the manufacturer website right now! Regular price $120, on sale for $78. Qualifies for free shipping. And can use promo code GIRLSGONECHILD10 for another 10% off your whole order.
From all the checking I've done this morning, the options carrier is nearly identical to the original carrier, so I'm ordering a second so we have one for each of our twins. This is even cheaper than the first one I bought at the REI anniversary sale. I'm stoked!
