Hi Planter,
Sounds like really good news for you.
Tell us more about your new shop.
These are purely academic questions that may help others in the same situation as yourself.
What factors made you decide it was a good opportunity.
Is it or has it been trading as a florist.
Is it high street, secondary location.
Is there a lot of footfall, traffic
Are there many other shops nearby and if so what type of shops.
Is there free parking nearby for customers
Does it have a forecourt for display or are you unable to display goods outside
Does it have rear access for loading/unloading or do you have to find somewhere to park and carry stuff
Do you have free parking for your own vehicles
Will you be tied to a long lease and is there a 'break clause'
Is the rent reasonable for the area/shop size
Does it have sufficient work/makeup area
Does it have a cold room/chiller or room to install one if needed.
Is it in good repair or do you have to redecorate/refurbish.
How close is your nearest competition in terms of a florist shop or market
How close is the nearest supermarket selling flowers
Would you describe the shop as small,medium,large.
Are you taking over any stock, tools, materials etc or will you be starting from scratch.

That's probably enough questions for now but there are loads more.

Cash registers...definitely BUY. They are not that expensive.
Have you got a business account with a bank yet.
Check out;

they have an arrangement with HSBC and offer very attractive rates for card processing. It more than compensates for the annual membership when you start processing a lot of cards.
You should be talking to your bank..like now..about things like card processing.
Champagne...talk to your local council. The laws were about to change when I enquired last year so was advised to wait. I don't know what the position is now but they will advise you.
Insurance..plenty on offer. We use Churchills for everything and have found them to be very good.
