I tried to buy a certain *******.io premium domain name. Searched the domain and it said Buy it now, I added it to cart then tried to checkout. It said something along the lines of "could not complete this transaction at this time, please try later". This happened a few times and I removed the domain from my cart and wanted to add it again and try again. Sadly Buy now option is not available and it says that this domain is only available trough auction. What has happened and what are my options now? It seems kind of silly offering something as a buy it now, then declining the transaction and moving the status of the domain or whatever.
It's possible that the owner of the domain name updated the sale type in that brief window or that there as some other issue with the premium listing. Otherwise, you might want to call Support so they can check the domain name in more detail.
