i would have taken pictures of the gecko along with the what ever you ship them in (using a camera the prints dates on the picture)right before you send them .heck that'll stop them from saying you send them sick and 1/2 dead.
Its a terrible shame this women is trying to pull something over on you.
Her email to you sounds to perfect...like something she's mailed out before.
She's trying to take you for some fool...and we all know your not. Dont let this lady get the best of you.
Try your hardest to bust this lady! Examine your photos well so you can totally for sure identify your girl Jane!
