I use Digikey, and chose 1st class mail for the shipping option -
it's cheaper and for me, on the East Coast, faster than UPS / FEDEX ground.
I normally get packages in 2-3 days, if I order by noon.
Also, I always get one or two or 10% extra, to allow for screw ups & to build my junk box.
Always look at rounding your order for any item up, as with resistors, etc
the cost difference between 10 and 25 of an item etc, is less than double.
