Why not offer huge packs of resistors or capacitors that cover all the bases like this?
I think Sparkfun is trying to provide parts that are harder to find. If they start trying to provide every component, they’ll never catch up to Digikey.
that being said you can get a lot of the products here other places. It might be nice for people who don’t want to make a separate order for something like that.
No disrespect or mocking intended, but their description got a chuckle out of me:Freak Nigh:

High-quality carbon film resistors with a connecting wire that is easily soldered.
SMD parts aside, I thought that all resistors came with “connecting wires”, they’re called leads. 
I would agree that it would be a good item to carry. There seems to be a trend towards DIY tutorials and addressing the needs of experimenters just starting out. Resistor and capacitor assortments are a natural for these kinds of people. The parts can be stocked very expensively because SparkFun can buy in bulk. It isn’t like they have to commit to ordering 10,000 units to make a profit. Well selected assortments like these represent a nice middle ground between carrying “everything” and specialty items not widely available.
I don’t agree macegr, I think a product like this is more their style and that they also dont offer things just because they could be hard to find. Seems to me they are trying to cater the hobbyists and amateurs and this would be perfect for them.
