I love Etsy for its seeds. They have seeds that I can't find anywhere else. I've also never had a problem with any sellers. Orders were shipped swiftly and arrived in perfect condition.
For some reason I thought that Etsy was some small ecommerce place for handmade crafts and jewelry but when I checked it out one day I noticed that it has many other things too.
I never browsed much there except for garden seeds. It's worth looking around I think.
