You know what they say "Fool me once shame on you. Fool me twice shame on me". Well, I have a third line on that and it's "Fool me three times I'll give you no more opportunities to get extra from me in any form". That means if someone wants to buy equipment IT or otherwise take the time to listen and consider the offer. Don't just blow them off otherwise you will have a hard time getting rid of equipment you can't use anymore.
