Hi Madison
You do not have to set up an account before you go, it is a cash and carry. however you will have to prove that you are trading as a business, so take along cheque book, shop utility bill, business cards. If you want to visit van egmond give them a ring (they are really nice and speak good english) you need to find out if there is a min speed, how much it is to ship a pallet?
If you want to visit the ones in the Aalsmere auction, it would be better to drive(do you know another florist not in your town to share costs and to help navigate) I have driven many times and it is not to bad. what area are you from? I am from Dorset so I go via the tunnel. It is 4.5 hours from Calais.Any more help required just ask.
