What is the effectiveness index of that script? why is it different from the other script? What makes it different and more successful? Do you have proof that someone other than you has already tried it? Excuse me, but when it comes to money you have to ask all the pertinent questions.
Instead of buying from OP, if anyone interested maybe they can shot a pm or ask Rhavar for similar bustabit's script (IIRC he still selling it if anyone interested, but forgot when he said that).
Update: lowering the price to 0.001 BTC for a short period of time.
Why lower the price if this is a good one?
Because OP realized this is not a good one and no one would buy it from him
