"go and see", "wait and see" - in each case both actions are performed. "Try and see" implies trying (or testing) and seeing, and is justified in "These are nice chocolates, try [one] and see [what you think]. In this case both actions are again performed.
But compare -
"Go and try and see" - do three things;
"Go and try to see" - do one thing and attempt to do another;
and then try to see which has the desired meaning.

Personally I'm puzzled by the store which advertises its prices as "30% less". I want to know which of their competitors gives the full 100% reduction.
