When I got my last job in 1986, I had a medium sized Craftsman box with a rather eclectic selection of Snap On,Mac,and Craaftsman tools from the 70's. I had another similar box for home use, as I replaced the Brand X tools with Snap On, the Brand X all came home. The KRL 656 box was my new work box. About then, I made the last payment on my house, then I could acquire a really decent set of work tools, so I started buying lots of Snap On.One secret of buying Snap On is to immediately see what is on sale that week. Sometimes, a discount of $80-150 was available because of the week's special. Every week, I always paid at least $100 toward my account and that was even if I didn't buy anything. He always bragged about me being his best account, and could buy anything I wanted and place it on my account any time I wanted. The way to get some saving on a Snap On truck, always buy what's on sale. Pay ahead on your tool account, and don't get stuff you don't need. A few months after the acquisition of the large chest, the top box came up on sale for about $400 off. I grabbed one of those, and then the KRL 291 side box came up for sale. Later, the puller set with the Lexan doors on the puller cabinet came up for sale, very heavily discounted. I bought the whole set, took it home, and even though I don't do much work around here anymore, I have all I need to do about anything on the race cars, my truck, trailers and my wife's car. Then, the two row roller chest came up on sale,I got it for almost $1000 off, took it home, offed it in the driveway using a cherry picker, that is full of engine tools, transmission tools, and rear end set up tools and air tools. When I retired from the City of LA, I drove my truck to work on my last day, took the top box off, used a fork lift to put it on a work bench, loaded the bottom box into the truck, strapped it in with a ratcheting tie down, then slid the top box in against a thick piece of cardboard and strapped it in. Made the truck sag a bit, but it all worked well.
When I got home,I used my cherry picker to unload the truck and assembled the tool boxes and I got it in the garage with about 1/2" to spare. I saved over $1000 by buying tools that way, get what's on sale, keep a high enough balance to qualify for discounts, pay every week, and the tool truck driver will look out for you and treat you like gold.
