Hi, I am preparing to upgrade from the current Nikon kit lens and intend to buy quality primes and zooms. Was looking at the BnS section and observed that the prices quoted for lenses without warranty were similar or more costly than brand new grey lenses from local online shops. Such online shops even offer shop gurantee. One particular online shop even offer to pay for repairs done at NSC! Has anyone faced issues with shopping online for greys, particularly the claiming of warranty? Cheers
