Did you tell them it was bought used ??

Last time I had a scope fail they were extremely awkward about it, wanting the original receipt, & then offering a much lower spec than the one which had failed, (that I had owned from new).

Even giving a 50% discount I bet they at least break even on the deal, due to the wholesale price, while you are out of pocket for however much you paid,
When you take a step back, I don't actually think that's a very good deal.

But hay if you're happy.
