Or are you considering international purchases?
My OP was made because i was selling a bike on gumtree for $150 i think but also said half price if paying in bitcoin just to see what interest i got from it, not one person wanted to pay in bitcoin but everybody asked "what is it"? Some researched it and came back saying it just looked to hard for them to bother with. I know its not that easy to begin with and it made me think with all the money being put in to bitcoin why is it still not easy for the average joe?
For someone who is not a computer geek and has not owned bitcoin yet, getting some seems indeed a hassle. (People recommend signing transactions on a separate computer, not connected to the internet, and then moving the signed TX to the main computer via USB stick. I presume that 99% of mankind would stop reading right there.)
It is surprising, but not TOO surprising, that a 75$ discount wasn't enough to drive people to do it. Maybe they suspected a scam or something? ("Is the bike worth 75$ only?" "Why is there a discount for paying with Drugcoin?")
If there is no discount other than the fees that the credit card takes from the merchant, paying with bitcoin is still not worth it for domestic purchases. Paying via bitcoin costs X = (bank wire fee) + (Bitpay fee) + (bank wire fee), whereas paying with dollars through bank wire costs only Y = (bank wire fee). Obviously X is greater than Y, and those fees will be added to the bare item cost, no matter who pays them.
It is not right to compare X to Z = (credit card fee). People normally pay merchants with credit cards instead of bank wire because it is easier, faster, safer (can be cancelled) , and delays the actual payment until after receipt of the goods. On these aspects, the bitcoin route is a lot worse than paying the merchant with bank wire.
The bitcoin route may save money on international payments, since it replaces one international bank transfer by two domestic ones plus the money-to-bitcoin and bitcoin-to-money conversion fees, which may still be cheaper overall. However, for international purchases the possibility of delaying and canceling the actual payment is even more important for the customer, so he will probably choose to pay with credit card anyway.
Bitcoin payment processors like Bitpay and Coinbase presumably know this, so they are targeting people who already own bitcoin and want to spend some of it. There are some 12 million coins already in bitcoiner's wallets; if each of them gets used only once for purchase through those companies, at current market price that means they would process 7 billion dollars and collect perhaps 70 million dollars in fees -- not bad.
To convince the average joe to adopt bitcoin, someone would have to pay the difference X minus Y for him. Some bitcoiners may be willing to donate their money to the cause, but companies are created to make profit, and they would never do that.
If you own 1 BTC that you bought for 10$, it is worth using it to buy a TV that costs 600$, because you will be realizing a 590$ profit in that purchase. Basically, whoever buys that BTC from Bitpay will be paying those 590$ for you. It would be almost the same thing as selling that BTC for 600$ on an exchange and paying the TV with that money.
However, if you then were to buy 1 BTC for 600$ to "replenish your reserve", that profit will vanish: you would be paying 600$ for the TV, plus several fees. If you don't want to reduce your BTC holdings, it is better to buy the TV with dollars, by bank wire directly to the merchant.
