This is what a schematic readability costs me: since I cannot read all the designators on the sch, I simply ordered every item qty 10, which is especially expensive when ordering capacitors as they are about a $1/pc. Instead of ordering the exact numbers. This brought the total order to $140 whereas it'd be more like $40 otherwise.
But then again, I prefer to have a stash of parts available for the future so no regrets.
