Hey there, so are you interested in my HMDX Flow Bedside Audio?
Hi, I'm interested in buying this. How many devices can it charge at a time? 
You can only charge 1 thing at a time, but you can charge a phone while you plug a different phone into the AUX-in to use it.
That's not ideal, but I guess it'll work. Would you be willing to accept $25 for this since it's used? 
I can do 30 if you pick it up from me, or $40 if I drop it off at your place. I'm afraid I can't go any lower though, as $25 would be a little too low.
I can pick it up for $30!
