Please note, discounts are given at checkout based on spend tiers. If you need to return an item you may fall below your original discount tier and will be credited back accordingly. Therefore, it may be possible that you return an item and you receive less refund amount than you originally paid. 

Example: your original order amount was $300 and you saved 30% off, but you return a $25 item and your order total is now $275 and therefore your refund will be credited at 25% off, not 30%.
