Depends on your truck guy. The old guy used to give me decent deals I would say, but my area just had a change of hands and it's getting pretty tough just to buy tools at full price in general. I love to keep my money local, but it's getting to a point where "I have a credit card and the internet and I'm not afraid to use them." I think I'll mention that to him next time we catch up.
Also, a lot of Caterpillar branded hand tools are made by Snap On, some are similar to their sister company Williams tools too. It's a crapshoot in pricing on Cat tools. Sometimes nobody notices them and you can get a smokin hot deal (1/4"=1 1/8" combination wrench set for $130), and other times people see the Cat name and the bidding goes through the roof.
I have a good mixture of Cat and Snap On tools mostly in my toolbox, Haven't broke any Cat tools but I understand the warranty is pretty much the same, you just take them to the Cat parts dept and you get a new one, may take a extra day or two as not every store stocks every tool, but sometimes the tool truck is out of what you need too. There's a Cat rental store in my town with service guys that can get me parts, so it's not as much of a hassle for me as it may be for others.
