Hee, hee. I was looking at that Digi-Key page and thinking that the sweet spot is at 1000+ where the unit price drops to $1.30. Of course, at $3 each, one would have to find 430 people repairing Mac Pluses who need C1 before making one's money back. But it's such a sweet discount over the Qty. 100 price...
Qty 1 => $3.03
Qty 10 => $2.60
Qty 100 => $2.17
Qty 1000 => $1.30
Qty 5000 => $1.22
Qty 10,000 => $1.13
The discounts in the unit price after 1000 are not compelling, but the drop between 100 and 1000 is close to 40%.
