I hope this is the right place to put this, my brother stumbled on to a coupon code for the following website:
code = WAVE10
it will get you $10 off Leatherman waves (when I checked most waves were already about 25% off retail)
so i did some digging and found a couple more coupons for the same site, here they are with descriptions:
RPSFS0108 = free shipping on everything ( I think everything)
MULTITOOL5 = $5 off all multitools
not sure if the coupons are combinable.
