Triple__Threat

I am just getting back into geocaching after a couple of years and decided to try out the intro app. I really enjoyed it and it prompted me to upgrade to premium. I assumed (maybe incorrectly??) that this would give me the better version of the app (it was the same price.) but it just enabled me to access all of the caches I see on my screen (none are locked) which is not what I intended to do at all. Why would I pay 9.99 to make the intro app slightly better when I could have paid 9.99 for the actual app?? Is this just a glitch? Should I have the real app?? Someone help!! I am so frustrated!

I'm from Canada and gas is raging high her its 1.39.9 a leter for regular its now costing me $140 to fill my tank. Geochaching is soon going to be impossible... unless they're close enough to walk that is.
