Overstock Reports Over $100k in Crypto Losses for Q1 2015
http://www.coindesk.com/overstock-reports-over-100k-in-bitcoin-losses-for-q1-2015/Here a are couple of main reasons retailers do not take Bitcoins.
1- They are still difficult to deal with. You have to figure out how to accept them, where to store them and where and how to turn them back into fiat currency.
Retailers do not want to sit down and study this all and figure it out they just want systems that will take a payment. 6-seconds done..

3- Bitcoin is unstable. It can lose 10% in one day. Retailers have tight margins 10% can make or break the profit in a sale for many.

People do not go out of their way just to make life hard for no reason. Especially when it comes to $$$. In the world of retail the payment is the final end of the line. It needs to be as easy and flawless as possible.
