tnd 510 vs 710

I have a hard time understanding how a travel center or truck stop would just give you 20% off a new product? This product has not been on the market for more that a few months and nothing has replaced it.

Why would a store take a loss on a new product?

Send me a copy of the receipt.

You can always E-Mail me the serial number. This will not affect your warranty.

Thanks,
Mark
