You should have pounced on that 7 Day Shop Kodak Gold 200 I sent you a link to, they seem to have sold out of all Kodak film now so you'll probably have to pay more now!
They've got 3 rolls of Fuji 400 in stock, so that should get you started. Have a look how their price compares with other suppliers (it's around 30p a roll dearer than the link you posted but you won't have to lay out £60 for 10 rolls - after all, you may find you don't like film photography!) but don't leave it too long or this will have probably sold out too!

I can recommend 7 Day Shop, I regularly buy film from them and they've never let me down yet, but allow 5 to 7 days for delivery if you try them.
If you want 200 ISO film then perhaps give this a try from Amazon:

If I were starting out and wanted a few rolls of film in stock, then I'd probably go for one of each of those two '3 packs' above, as it will give you a choice of 400 and 200 ISO film. Plus, it will work out about the same price per roll as your bulk pack of 10 x rolls of Fuji, and you won't have to stump up £60! I think that Kodak Gold 200 is very nice film for the price too. Here's a shot taken with it:
