Hi Becky.
Yes, I'm aware of their shipping backlog as I am on their mailing list. When they announced the sale, he stated that he wants to get these orders out the first week of July. The link above is only for the special sale.
These plants were ordered before his daughters cancer diagnosis. If he were to cancel the grower order, he's looking at almost $2,000.00 in restocking fees, so he decided to 'fire sale' them to make room for other stuff coming in. As fate would have it, they were just getting back to normal from the winter disaster (they lost most stock and greenhouse space the winter of 2014/15 due to heavy snows) when his daughter's condition worsened. He's splitting time between the hospital and trying to save his business, which is his only source of income.
I actually have an outstanding order with them from their 'SaleForPlants' site for some unique hosta that I purchased back in the spring. Personally, I'm fine with the shipping delay on the order as I have to find room for the plants anyway.
