Seems simple enough, if you have a pair of RMs you don't wear any more get $100 off a new pair you might love more. Can be done instore for immediate appraisal and voucher issue, or online (but you need to post them back and await processing).
To save some questions:
- Boots must be a complete pair and in 'wearable condition' for which authenticity can be confirmed
- It looks like you can redeem multiple pairs for more vouchers
- You can't stack vouchers, only one allowed per purchase of new boots
- Applies to full-priced boots only (i.e. not to other apparel or boots on clearance)
Important to note the voucher only applies to any full-priced boot, most likely does not apply for boots on discount.
