companies who fail to live up to their end of the bargin in a bitcoin world won't survive long. I've been shopping on the internet since the 90's and not once have I had to place a chargeback.. Chargebacks are mostly fraud and people wanting shit for free.. In turn goods become higher priced and that cost is passed onto all the other customers.. Anytime I have been unhappy with an internet purchase the company has always given me a refund. The need for chargebacks is truly minimal. Any company that wants to keep their customers is going to issue a refund. Companies that won't are shady and need to go out of business anyway.
