From what I understand with Killer Instincts policies, With the Bowshield coverage, even dry fires are covered as well as labor. However, strings and cables are chargeable but with a 10% discount. Shipping is the responsibility of the crossbow owner.
Q: Am I responsible for return shipping on a warranty claim?
A: Yes, whether the crossbow is shipped back to the dealer or to KILLER INSTINCT™, shipping is the responsibility of the customer.
With that, I assume the $100.00 you are saying it will cost you is for discounted new strings and cables and shipping charges.
Their price on strings and cables are listed at 39.99 each, with a 10% discount that would be a charges of $72,00. the rest would be shipping charges.
Best to fully understand manufacture policies before any purchases.
However, upon inspection and being a new crossbow with the additional warranty, with a result due to a manufacture defect, perhaps killer Instinct will do better.
I understand your frustration, but ranting on Crossbow Nation will not get the issue resolved. Work with Killer Instinct and hope for the best. Let all here know the determination and causes of the damages and the final results.
Good Luck.
