Who are you kidding?? This isn't minor hardware...these fittings are ~$5 a pop!

Priced individually:

  | Fitting | Price (ea) | Qty | Total |
  |---------|------------|-----|-------|
  | T       |       3.34 |  12 | 40.08 |
  | 90      |       5.79 |   4 | 23.16 |
  | 45      |       4.95 |   4 | 19.80 |
  | 180     |       4.95 |   2 |  9.90 |
  |=========|============|=====|=======|
                         |  22 | 92.94 |

In contrast, the bundle lists for $88.10...that's a lousy price delta of $4.84 (approx. 1 fitting). In consumer hoodwinking terms, it's the equivalent of buy-21-get-1-free...except the "value proposition" comes at a cost of zero optionality and overweight T fittings.

If you've got the cash to burn on benchstock at this price point, more power to you, but the point is you're really paying a premium to throw away choice for the illusion of value with this bundle.
