Does not work in FL, Sitka and some others. I placed an order for some Superfeet and a MicroRocket and was about 10¢ short of my $100 to get $20 off. Added the free cap with $75 purchase and it put me over the $100, gave me the cap for free, the discount and still was able to use the Rokslide code for extra off. Got it all for $74.40.
