Isn't $1.5m is way much too expensive for a $47k in 6 months average revenue or $94k annual revenue? Or let's just round it off and say it is a $100k a year.
For $1.5m the estimated ROI date will be 15 years. Isn't it way too long for having business? I'd bet 3-5 years ROI is considerable for any business.
They have the right to ask any amount they want for their product. You never know what someone will pay until you throw it out there and see if it sticks. I don't think 1.5 million is gonna happen, but I wish the seller luck.
Is there any proof of what's been posted so far or do interested persons need to contact you for info?
