Not sure about the parking issue to be honest, but I can't help thinking that your timing is awful. Unless you can get stock before 20 November, all your stock will need to be TPD compliant. You will need to get any of your own juices approved before you can sell them (with all the associated on costs), or you will have to sell juices from established suppliers who have got the necessary approvals. Either way it seems to me that your margins will suffer as a result. Most experienced vapers have already future proofed their gear as much as possible, or are waiting for bargains as established shops try to shift their non-compliant stock before 20 May next year. Either way, I cannot see that there will be much of a market for atomiser hardware until well into next year, and that is without the weak pound either making imported gear more expensive or forcing you to squeeze your margins if you want to stay price competitive. I think the next twelve months will be difficult for established enterprises with loyal customer bases, let alone start up businesses. All that said, I wish you well.
