$3.50 for 100 of any value. 5% tolerance. Is this too good to be true?

Not much of a bargain. This price is about three times retail at a regular distributor.

Remember, the 1/4 W parts are only rated for 250V.

They were advertised as "carbon resistors." I wrote to them and requested that the order be cancelled if they are "carbon film."

Thank you,

You can tell from the photos that these are film resistors.

Nothing wrong with using them to replace carbon comp parts in old radios.

On the rare occasion that you actually need a composition part, you might consider bulk cermet or ceramic composition, instead of carbon composition. A bit spendy, by it will stay on value much better than the carbon.

Try to be happy that you can get suitable parts incredibly cheap. Don't count on this happy circumstance continuing. SMT is taking over, and parts with wire leads will become low volume specialty parts.
