Well, at least you actually let them know that you will verify information when you get home from work rather than inputting false information in the first place, intentional or not. The notion of a typo doesn't upset as much as the nonchalant attitude about him making one in my case. "Woops, well whatever" broke the deal on my transaction personally.
No, not, "whatever" when I'm sending someone I don't know a $300 check....that doesn't quite make me feel comfortable about any transaction.
There are a few things that most serious buyers take into consideration and if you mess them up from the start it can be a bad situation. Age. Genes. M/F. Health.
It's four things to remember , it's not like you're creating an ad for a 1970 Superbird....not to say at all that remembering that much information for that many animals is easy by any stretch however. Mistakes happen, but if you're doing business as someone not as well known it can certainly hurt you down the line. Like you said, your word as a breeder is absolutely critical.
