It's not that popular online. Like as in online shops. Just try and see how many online shops that accept bitcoin you can find. I mean the list is growing by the day but still bitcoin payments are still in their infancy. But still, from what I can see things are looking up, slowly but surely.
I think the online store will not be used every day. you can not be spending then always pay the shipping costs continually, perhaps if it had been a lot of offline stores that accept bitcoin we could use bitcoin everyday
