 		 #155594 - stupid boss
Responding to: ???'s previous message
The boss probably got a good deal on those shift registers, and has a barrel-full in the stock room

If you base new designs on what you get "a good deal" on or what you have in the stockroom, you will invariably be screwed some day.
"a good deal" could mean counterfeit.
"have in the stockroom" could mean discontinued while you still produce the thingy.

I can see the above (deal/stiock) possibly being meaningful for parts that actually cost money, but to be this stupid to save $0.11 takes the cake.
