Just joined RW & tried to use Coupon code from givingassistant.org/
RW Chat support said, “No relevant RW arrangement with GivingAssistant - so coupon offer is Not valid”.
Kinda curious, however, Code Rejection that popped-up was: “This one-time Code has already been used”
Not: “Invalid” or “Rejected”.
To a RW newbie … just seems a bit odd!
Moderator’s note: Link to coupon website removed since the coupons are not valid anyway.
