The shop supports refunds and exchanges according to its refund policy. Specific return window details are not explicitly stated, but support is available for product returns.
Why is my One Car Stereo promo code not working?
Most often the code has expired, or a trailing space came along with the copy and paste.

Re-copy the code from the list above, clear the field, and enter it again.
Can I stack multiple coupons at One Car Stereo?
Almost certainly not. Nearly every checkout accepts a single discount code per order, so use the highest-value code that applies to your basket rather than trying to combine two.
