I will end with this comment, clearly you have been burned in the past. Sorry that happened, but any real business owner knows the damage a single customer can do to a business. No reputable company is going to scam anyone, with the possibility of a credit card chargeback, the risk is still very high to the business owner, not the buyer, the risk ratio is so out of whack to do that it doesn't even remotely make sense to scam someone.
if your not doing your due diligence vetting the sites your buying from when the item is 40% lower than any other site, sorry that's on you.
Respect is a 2 way street.
