Do the simple ratio
Warranty price ÷ product price. Above ~15–20%, be very skeptical unless there’s a special case.
Also compare to the manufacturer warranty already included (often 1 year).
What’s actually covered?
Wear, misuse, cosmetic issues: often excluded. Read exclusions before you sign.
Keep receipts and serial numbers even without an extended warranty.
Cheaper alternatives
Credit cards with purchase protection / warranty extension (depends on issuer).
Personal emergency fund: set aside the warranty amount instead of paying for it.
Link to deals
A $100 discount erased by a $120 warranty isn’t a deal. Calculate the walk-out total.
On PromoSimple, compare the bare product price — add extras yourself.
Default: no. Rare exception: fragile product, heavy use, short manufacturer warranty and a clear contract. Otherwise, keep the discount intact.
