Although not all specifically offered as such, we have the following options, certainly missing some that would have been preferred, but at least covering a variety of price points:
1. If you think it's worth it, buy it.
2. Wait a year and hope it comes down in price, as has often happened with these pricey box sets (Beatles, Rush, Kiss, etc.).
3. Buy it now and sell it used at a later date.
4. Keep an eye on ebay for someone willing to sell just the blu-ray.
5. Get the right streaming hardware and a streaming music subscription and stream it.
6. If none of the above work for you, learn to live without it.
(I purposely left off any of the illegal and/or more unsavory options.)
