Hi Tony. Subli Nation are still trading, as I had something delivered from them yesterday.
They don't appear to be selling direct anymore though, but through a distributor just north of Hull. Their trading methods seem quite bizarre at the moment and must be costing them a lot of money.
Subli Nation was hoping to have fifteen mini distributors in place by July of this year, but it never happened. To be realistic, the UK market for sublimation products would not have been big enough, for that to have ever been a viable proposition.
The service from Subli Nation and their method of trading as really gone downhill over the past three months. If it hadn't been for the fact that they had a specific item I needed, I would have had reservations about dealing with them again. The news article you supplied, validates that concern.
