I think that this will happen soon, because taking bitcoins by sellers will lead to higher prices for goods because of high fees. For small purchases, this decision will be very unprofitable.
I'm guessing you do not own a business. I only use bitcoin and it has led to lower prices. I expect to pay 1-3% less if I use bitcoin. The businesses I work with have seen huge profits because of bitcoin. The fees on credit card transactions are high compared to bitcoin fees not the other way round. Not to mention the many rules about who you can deal with, what you can buy, where you can shop, the ever-changing contract terms, the penalties, gotcha-fees, the risk to your identity, the 2-180 day wait for clearing the transaction... You get the idea.
