what does this mean

[ylun]

I want to get the retro valve from the online store, on the bottom fo the page I see this:

SAVE TIME ON GO RETRO! Give us the serial number of the valve you will be turning in on the Message line when you are placing your order.

what does this mean? One more question I want to know is there any special going on now like the trade in your guys had before???

Thanks

that is for traiding in your old AIR valve, it's an upgrade price. personaly i'm not letting go of the valve i have now, it works too well, i'll get a retro some day but then this valve will go in another mag.
