I contacted crutchfield and was told that the following coupons have expired:
Crutchfield free shipping PA145 Unknown

The Following code is still working although they would not give me the expiration date.
Crutchfield $10 off $50 or $50 off $250 PA440

that's not true. for example PA166 still works for some items. remember that these coupon codes do not work on all items.
