In my original posting, I did not include photos because I had the product safely stored in the original box and right now, the website won’t allow me to post them. Due to the multiple inquiries from interested buyers, that requested photos of the Parasound Halo A21, I have removed it from the box and now have available photos. If interested, please contact me and include your email address.
For those that have asked me about Paypal, this is the information I found on their website regarding fees and who pays them. “PayPal is free whenever you use it to buy something. The seller pays us a small fee to securely handle your payment. As a buyer, you never pay a fee to use PayPal.”
Thank you
This Parasound Halo A 21 was taken out of its original box, and it was used for no more than the installation set up process. The speakers that were to be used with the Parasound Halo A 21 were never obtained. This is the reason for selling it. The Parasound Halo A 21 is in perfect condition. It comes in the original packaging with all of its contents.
It has been kept in a very clean non smoking environment.
Please feel free to email if you have any questions.
Thank you.
