When a customer returns a product that you referred through Boots Affiliate Program's affiliate program, it could potentially impact your affiliate commission. Boots Affiliate Program's policy generally states that if a customer returns a product they purchased through your affiliate link, the commission earned on that sale may be reversed or deducted from your account. This is because affiliate commissions are typically based on completed and confirmed purchases. If a purchase is later refunded or returned, it might lead to an adjustment in your earned commission.
