We must know how long your offers are good for so we can decide if we do want them or not.
You have be TRANSPARENT and HONEST.
We do not like SURPRISES.
Please be HONEST and UPFRONT.
Do not forget to being TRANSPARENT.
I am writing this as your offer here is for ONLY SIX MONTHS. Nobody wants a short licensing period.
Thank you.
