I have bought a few plants from OZ over the years. I have never been disappointed. They were either picked by myself or off eBay with good pictures showing the plants. No surprises.
I have to say though it has been my experience that they are rather hard to reach and do not respond very quickly to phone or emails at all.
One more to add, since I like to see my plants before buying, they seem to have stopped posting pictures of plants they list on eBay.
I think currently or just up until recently I remember seeking Roth, Gloria Naugle, Alexj all of which had a representative picture, not of the exact plant.
And Franz Glanz, show two pictures of flowers and no plant pictures. At $150, I have to see the plant and know its condition.
I know it's a work to add individuals pictures for each listing but I hope they understand it's a part of investment to their business ( and relatively small one at that) and showing photo of exact items being sold is a main attraction for people who shop on eBay.
