In my industry it's the big players undercutting everyone else on price and keeping them out of the market. It's hard to even make a buck on some items. I did the free shipping thing, but then learned that I was losing a lot of money with that and dialed it back.
The second is advertising on niche sites etc... again you have the big boys playing in that space and they get exclusivity crowding out the market. Some sites will let you advertise, but I'm finding the the conversions rather low.
