finally we returned a piece of gear

Yesterday, after being off the trail for 5 months, we returned our sleeping pads to REI.  This returned should have happened while on the trail because they became defective on the trail.  Nightly, we woke up needing to blow up our mattresses or we're woken up by an uncomfortable sleeper (typically Canada) blowing up a deflated sleeping pad.  Gear is essential to a successful & comfortable thru hike.  It's common because of the daily use of gear that it breaks while hiking on the trail.  It's also common practice for thru-hikers to angrily contact manufacturers and stores and request new equipment.  Typical to our form, we didn't return any of our equipment on the trail, we waited until we returned home.  Yesterday, while at REI, the worker offered to replace our sleeping pad and we opted for the cash back- $122.  Because for now, we don't have a need for a camping sleeping pad, we have a comfortable bed. What else can we return?
