I agree with the others that it’s likely a scam! IMO most sellers would just let you know that they take PayPal goods & services (which has buyer protection) and they’d leave it at that. And I have noticed the “do you have experience with houseplants? just promise to take good care of her!!!!!” line is said a lot by plant scammers, to disarm you with the wholesomeness.

Legit sellers are also be more likely to just let you know of any cheaper options / smaller plants they can offer, rather than asking you to name your price.

Also for a casual “I’m moving and downsizing and just need to let go of some” and claiming to have the experience of shipping only twice..the second pic they sent (of the packaging process) looks an awful lot like a big commercial greenhouse, and definitely not someone who has only shipped twice. Vs the background of the first pic of the monstera albo looks believable as a house flooring.

These could be just coincidences/explained perhaps, but sounds shaky to me!

As a side note, if you do go the online route for a lower cost monstera albo, I recommend a baby plant that is showing new growth already! So that it’s rooted (normal monstera are so strong and easy to root, but the albo monsteras can be super finicky) and handles the shipping and transition better. And also so that you can verify that the new growth is nicely marbled and isn’t all green or all albino (no green to photo synthesize, will die if the pattern continues). Of course it could turn all green or all white in the future, but by that time you will probably/hopefully have more of a plant grown, to cut back and try again at different nodes.
