Genuine Sony System Audio RM-AMU003 Tested. eBay buyers: Understand that you’re purchasing from an individual in a secondary market. I do not buy from Goodwill bins. Sometimes items that are new with tags will show signs of handling. Used items will likely show slight wear. Any obvious damage will be listed. All measurements are approximate. I am willing to consider an offer a couple of dollars less than my listed price, but not much more than that. That being said, I will consider all reasonable offers. I would appreciate your prompt payment. I do not negotiate shipping fees as part of offers. Those fees are set by USPS. This item will be shipped in an envelope when possible in order to reduce your shipping cost. As shipping fees continue to go up I try my best to save you money. If you would rather it be shipped in a box please notify me prior to paying and your shipping fees will be recalculated. I will try to place your item/s in the smallest box possible to save you postage. I also purchase/recycle the lightest boxes possible for the same reason. I research the current market on the item/s I am listing and try and list for the best price possible. Rarely do I do markdowns if any, as my prices are already low. All of my measurements are approximate. Often my colors are not exact because I am taking pictures with a phone. Please let me know if you have any questions regarding this item as all sales are final. I consistently strive to deliver outstanding customer service. Just a reminder that USPS is running very slow these days.
