I had a strange experience with a tag. I got this orchid and after it flowered I contacted the seller and said that the tag doesn't match the plant- the plant looked like x. He said he would contact the breeder. Well after 2 follow ups he said the breeder said that there had been a mistake, and I was right - and I should just manually change the tag. I said !!. He sent me a new tag.
Then there was the major online retailer selling a plant with the wrong grex listed online. I knew because I had just bought the plant ! I e-mailed him 2x. No response. Then I called him and pointed out the problem. He thanked me profusely and got it changed on the website - after telling me that nobody else had picked it up in the last year.
Based on these experiences, and others, its no wonder I am a bit sceptical about what goes on in the industry.
