so...it's a store showcasing products from other people?

Yep. It's called an affiliate store. I just added everything llama-related I could find on Amazon, and that way people who want shop for llama stuff don't have to sort through thousands of unrelated items such as books in Spanish (there are thousands of them with the word "llama" or "llamas" in the title that have nothing to do with the animal). There are also a lot of items on Amazon with wrong keywords or pictures or in the wrong category. My store corrects that issue because I checked all the items individually and sorted them myself. =) It's a lot clearer and easier for someone to shop for llama items in my shop than to try to find them on their own on Amazon. I've spent nearly 100 hours on building up this store. And if I sell anything from my store (or, thanks to cookies, if you visit my store last and then buy something else from anywhere on Amazon within 30 days), I make a small commission. It's only 4% right now, but if I sell at least 7 items, it jumps up to 6%. =) So if you want to help out but don't want to buy anything from me directly, you can shop on Amazon or advertise my store and I still make a little bit. =)

looks a nice deal...and one day you can start sellin your own llama stuff :p
my paypal account is still zero (and if nothing unexpected happens, it will stay like that for a long time...you got yourself a poor friend xD), so I can't support directly your store...
does AdSense works with Amazon?

Not directly, but once I have enough to buy a domain name, I can incorporate both into that website. I have several other stores I'm affiliated with, but I haven't had a chance to really set up the links on a website and whatnot. I have some of them on my temporary site at EverythingLlamas.siterubix.com, but once I have a dedicated website, I can make a full-on store with links to items in other stores that are llama-related or useful and sell them all together. =)
