Wandered into my local Costco to see if they had this sound bar and at what price. I had seen it at $130 previously, eBay had it for $125 (open-ish box), so I figured I'd give it a shot. This sound bar is no longer on Costco's website from what I could see but they can be found around.
Low and behold I see the LG SHC4 300 Watt 2.1 Sound Bar System for $99.97 + tax (if applicable). I scooped it right up, it's an older model but has HDMI connectivity that can be hard to find at this price point (IMO).

I've tried uploading my receipt, if it worked you have visual proof. I suggest calling your local Costco to confirm availability and price, and I apologize for not taking a photo of the price plaque. It's a Saturday at Costco and I wanted to get out of there.
