Did you try calling the billing line to see if they'll refund any of it? I had something similar with an old gym membership and they actually gave me half back once I showed them the statements. Took some patience on hold, but worth it if you have the receipt handy.

Toss in some activated charcoal too, that stuff pulls odors like crazy.

Oh come on, is this really ruining the hobby? I get that the app was bad, but that's just one bad app. You can't blame the whole idea of cloud identifiers because some developer rushed a half-baked product out the door. It's like saying all maps are useless because your GPS took you down a dead end once. Cloud spotting is about looking up and using your eyes, not staring at your phone screen anyway. Maybe just stick to the old field guide method and skip the apps altogether if they're gonna stress you out that much.

Honestly, the Reader's Digest condensed ones are the absolute worst. I fell for a similar box once and it was packed with those tiny brick books and a bunch of old Reader's Circle hardcovers that looked like they'd been stored in a damp basement. Ended up giving most of them to a used bookstore that barely wanted them. You got totally burned on that $15.

Plumbing's really not that complicated man
