Lets see (thinking long term here) Sarich & Talbot get in for large amounts at 40c. Do you think they intend selling at 45c? Doubt it.
Your mate in at 42c might cause him some short term grief associated with you taking the mickey out of him.
Now say you get yours at 34.5c. Are either of you going to give a Flying Fig in 2 years time what your entry price was?
