they used to have an amazon store, but amazon kicked us out for some reason. to sell there i think you need an actual retail store, partly because if you print something and the customer doesn't like it, you foot the bill for the item. and its abused in amazon. you'd be better at selling on ebay, printing it yourself.
your also lost in amazon, because they only use titles as search words and if you don't have a good set of ratings, your lost in the back. many companies give away their products just to get a ton of reviews, stacking the deck.
when we were on amazon, i don't remember a rush of people finding me, but its hard to say if it helped at all. i do know i'm there under another store - and it does not help me sell anything.
i'm not sure what the 99 cent thing is, i do know they want like 15% of the price, which is why everything there is more expensive.
