Is it normal to wax your legs using duct tape?

First time waxing my legs.

I've used duct tape because hair removal wax is super expensive.

People don't seem to advertise that this can actually be done, and that the final result isn't that bad. Of course duct tape doesn't remove every last hair; I just want to do the bare minimum to not look like a hairy ape in public now that spring has sprung and bare legs are a thing once again. Besides, I'm single, and nobody is going to be inspecting me with a microscope.

Is there a reason why people don't talk about doing this, though?

I for sure won't be doing my underarms this way, because that would probably hurt.
