Every so often during the year we offer coupons. They vary in discount, but they've been between 25% and 30% off in the past. They can't be combined with any other discount, so like if you were to do a buyout review you wouldn't get an extra x% off, it would just be the 30% you get with the buyout. They'll be emailed to you, but if they don't show up in your email you can email JR to get them. I'm not sure when the next time we're doing a coupon is, but somebody will announce it in the forum when we do.
The best way to make sure you get the next coupons (when they come out) is to sign up to the newsletters (if you haven't already) and add the email address they come from to your contact list so it doesn't filter to the spam folder.
