Because they're in a bag marked with the types and date.
Seriously, try Chris on Monday, they have a terrific stock of Wima's.
Their motto is "Purveyor of Mundane Parts" They have caps, resistors, some semi's, but lot's of stock and cheap prices in reasonable quantities.
IF they won't sell you four, send me an email and I'll have Pete send me
samples and then I'll send them on. Or tag 'em on an order or something.
We probably buy $3K worth of parts a month from them. $3 in caps shouldn't be too tough.
