BTC, that's a 5% difference. You're using deflated figures, localbitcoin isn't a valid source, of course people put in a profit margin, I'm not going to sell you a bitcoin for free...
People are making good points and rather than seeing them and try fixing your mess you keep deflecting. Of course having to pay more than $1 to get $1 has an effect, why would someone pay $1.15 to be able to buy from your online store at a $1 value?
