In your original post, you stated "soon" and to many of us here, soon could be as quick as tomorrow. I know when I say "soon" it means I already have the hab set up and temps running, the debit card is already out, or the snake is already on its way. I know many of us here have had our impulse purchase or two, but the people who buy snakes that way are seasoned, have the means to do so, and have been elbow deep in this hobby for many years. And almost everyone here, even with our differing opinions, methods and tastes, are incredibly passionate about what we do and are always concerned about the welfare of every animal, be it ours or someone else's.
When we see someone who has just relinquished a snake for lack of experience, funds or what have you, already looking for a new addition it will definitely cause a word of caution. Don't take offense, it's rarely ever done with malicious intent.
Take things slow, get the experience you need in case any future animals cause issues for you again. You never know what you're getting until you have the snake in front of you.
