They typically don't officially comment on future coupons, but based on the past, the 20% coupons usually come in March, May, and November. Several big ticket items are often excluded (bikes, cargo boxes, kayaks, etc.) and you'll just have to read the fine print on the coupon when it finally comes out to be sure. That said, I did successfully use a 20% off this last March to buy a Saris SuperClamp EX hitch rack, so you may have luck on that.
one or more gifts or other benefits from the co-op.
