I make a note to buy myself one or so each year and end up spending all extra cash on my father and fil and never have any left for myself until after the sale ends.
Sears usually had good deals on tools, they may make up a 13 (or whatever number) piece wrench or socket set in a fathers day specific package then after fathers day it will go on clearance for half price. Then they will make the same 13 (or whatever) pieces in packaging for the next holiday and it will go on clearance the same way. I made up my truck toolkit that way.
