how do you get the coupon, is there a code to type in
I think the coupon expired last week. I'm not seeing it now (it was a check box to click just below the price summary). It's still 20% off though.
I actually bought one on the sale with the coupon, and it arrived yesterday. It's better quality than I was expecting. It's not my Swaro or Zeiss level, but I'm happy with it for the $83 I spent. Will be putting it on my 25-06.
