Dennis has bought from me off my webpage sale list a few times over the past few years. The transaction is an endless list of questions, unsure commitment, requests for holds, long delays due to vacations, being out of town, etc. I never send before receiving cleared payment, and - eventually - he paid up for most of what he'd asked about and I shipped them out. The last time it was about four months. Then last year towards the end of the year he sent an urgent note about being ready to pay for plants he had inquired about in the spring. I had sent him a note in the summer stating I could not hold the plants and to notify me if still interested (I had a big in-person sales opportunity and wanted to unload as many plants as possible). When I got the email from him four more months later, I just told him I had sold the plants (I had in fact sold most of them). I was worn out trying to deal with him. I try to be patient and flexible with potential customers; many of them are my internet friends of long acquaintance, people just like me. I am not perfect and have missed a shipping date or two in my day, but at some point you just get too tired of being strung along.
