yep, next day shipping is the only way to go. its pretty much a gamble if you get into the 2 day shipping. anything ive ordered next day shipping has always been good. except if you ordering from algae barn and you are ordering nano brine. ive had 3 different orders with nano brine and have doa on every order.I ordered twice. I would not order again without paying extra for overnight shipping. My last order (2 day shipping) arrived on time but almost everything was dead. Packaged/insulated poorly.
I’d definitely try to get snails you know are alive at your LFS.
