Well, to be honest, there’s a lot of info online now, so it’s not really hard to find specs about the thing you’re looking for or currently browsing.

Though I do agree about construction advice. Like you’re trying to do something around the home and these people were really helpful, I mean they really knew what they were talking about. Sometimes, you could just go in and be “I wanna do so and so, what do I need to do that and how do I do it”, and the emplyees would just take you through isles and tell you to get that and mix it with this, then add water or whatever, do that, etc.
