Hey there, nice batteries, are these new?
Yes, they are.
My budget's closer to $5, are there any special incentives?
These are already priced to sell! $10 is a great deal. I don't have anything extra to offer at this time.
So I could just buy it from the vendor elsewhere for $10? Does it at least come with the extended battery cover?
No; these are already marked well below market value. Each battery comes with an extended cover. It also has extended capacity, meaning it will last longer than the average cell phone charge.
